Another pretty good day in the shop.  The shocks and brackets and the brake kit came in yesterday. I went out there to start mounting the shocks, or at least get all the brackets trimmed and shaped to fit and get ‘em tacked in.  I got the lower mounts done and was starting on the uppers when one of my neighbors from across the street pulled up in front of the shop.  He had my driveshaft loops and the crossmember for the rear loop in his car!  The stuff had been addressed incorrectly and was sitting on his back porch in the rain!

I stripped all the wet cardboard off of everything and wiped it all down.  I put the shocks aside and went to cutting and fitting the new crossmember.  This one is made so that the loop can be unbolted for removing the driveshaft.  I had a little trouble getting everything cut down, centered, and lined up properly, but after one try that required cutting the tacs off and starting over, I got it all like I wanted it and welded in the stubs, drilled them for bigger bolts, and welded in the crossmember. I may trim another inch off of the rear loop.  I jacked up the back half of the car and the rear axle only dropped about an inch.  There's three inches of loop[ below the driveshaft at that point, so I think I'll go for a little more ground clearance there.

Got band rehearsal tomorrow, so I doubt I’ll get out there to get any real work done.  I’m planning on finishing the front loop and getting the shocks mocked up and everything welded in place on them.  My headlights are supposed to be here tomorrow!  Gonna be interesting to see how I can mount them up and make ‘em look right. Friday should be a busy day!!

As usual!  Pics when I get ‘em downloaded and edited.

Another pretty good day today.  I set in on installing the front shock pieces.  I’d bought a pair of upper shock mounts and a pair of chrome shocks with just over 5” of travel.  My plan is to give this car a little smoother ride than Lockjaw.  I jacked up the car and measured the drop in the front suspension.  It only dropped an inch and a half!  I set one of my ramps under the right front wheel with a 4”x4” block on the ramp. 12” high on that side and the left front was just touching with me sitting on it.  With the shocks fully extended, they still had a little room to spare.  After caging the shocks at 2 1/4” down travel, I mocked ‘em up and checked everything again.  I cut 2” off of the upper mounts and tacked them in place.  Then I positioned the lower mounts and tacked them in too.  I checked everything once more and then removed one hairpin at a time and welded the lower mounts on them. I decided to add a brace between the bars to spread the load created by the shock action. 

I moved the driver’s side track bar bracket up about 1/2” to level it out.  Looks better and will work better too!  I welded the upper mounts onto the frame and then reinstalled the hairpins and the shocks. 

I went to put the thing back on the ground and my floor jack wouldn’t pick it up!!  Low on hydraulic oil!!  Reckon I will have to go get some in the morning.

Pics as usual when I get ‘em edited.

Mostly just cleaned up the shop today. Tried to service the floor jack, but it appears that it has more problems than low fluid.  I’ll take it to be repaired next week.

We tried something new with the tubing bender today.  Made a loop for the Model A to hang the pedals on. Turned out pretty good after we figured out what adjustments needed to be made.  I didn’t take pics of it yet.

I had Jeff cut down the front loop for the T and I welded it in.  I DID get a shot of it.  I think we swept up five pounds of grit where we’ve been cutting and shaping parts for both cars.

I think I’m getting back into shape most of the time, but I was just short of worthless today!! We only worked for about three or four hours before I had to call it a day!!

I did a little straightening again yesterday, but mostly just kicked back and watched some racing.  Tried to watch football, but the home team was playing so lousy that I switched to the Indy Car race.

Went to Jeff’s for supper and to pick up another floor jack.  Food was great and the jack is BIG!

I decided to concentrate on the rear brakes today. I’m adapting the rear disc brakes off of a 1996 Caprice cop car.  I bought the car for the transmission and the fuel injection and I got rear disc brakes and all the electronics and harnesses, plus a nice big tub full of small parts and stuff in the bargain.  The car was only $350.00 and I could drive it!

I had already started on this months ago and got sidetracked with a hospital episode. When I got back to it, there were a bunch of other things I needed to do and it got put off.  Now I’m down to a few items that need doing before I strip everything off the frame and flip it over to finish all those things that need to be welded from the bottom.  If I were any good at overhead welding, I might not have to flip it, but I think it’s a good idea for me to do what I know will get it right.

Anyhow! I fell in on the brakes and re-drilled the backing plates to fit the Oldsmobile axle tubes and modified the axle retainers to clear some of the stuff like parking brake actuators and casting bosses that line up the parking brake “shoe”.  The shoes are actually rings that expand when the parking brake is applied.

I had to remove some material from the backing plates, (they appear to be cast steel or cast iron) where they have extra material that won’t allow an axle retainer to lay flat.  These brake assemblies are originally found on rear ends that use internal axle retainers, (C clips) so the castings have reinforcements that aren’t needed with a steel outside retainer.

I didn’t take a lot of pictures because if you do one of these, it’s probably not going to be on one of these old rear ends.  I’ll add a few more pics as I finish the other side.  Incidentally! The backing plates are very similar and they mount differently.  One mounts what appears to be upside down! I got the passenger side all put together, up to bolting on the caliper brackets and calipers. I’m doing it in small steps to make sure it all gets lined up correctly and works right the first time.

I got tired and stopped when I got the rotor on and the wheel installed.  I’ll get back to it Wednesday.  Doctors tomorrow.  Pics later
