The body mounts really made a difference. It feels less of a "bucket of loose bolts", and more solid.

I have been driving around, going for small errands, enjoying the car, before the next change, see below. It's a 3.73, limited slip 7.5". A bit overkill with the cover, but once all assembled and painted black, will look and feel ok.

Can't wait to see the difference with a 3.73 / 200-4R.

Got beautiful Speedway Seville-style calipers, etc.

Before I start welding the caliper brackets on the diff, I checked for clearance between my Pontiac 15" wheels and the calipers, and it will require a spacer. I already use a spacer for the looks, now it will be a functional thing.

Also, note to self: check clearance for the lifesaver spare tire. I have bad memories about that...!

Slowly removing the old diff. It's been years, but I did remember things such as - 3/4 socket for the lower shock bolt; 1/2 socket & key for the upper shock mounts; and 9/16 socket & key for the sway bar.

Next up - removing the parking brake cables, then the brake line, driveshaft, finally the lower & upper control arms.

Order from Summit came in - upper / lower control arms, tires, 3" trim rings, etc.

Tire order is messed up - I ordered four 215/70R15, but ended up with two 215/70R15 and two 215/75R15 :/

I will have to deal with this. Would have loved to have 70s all around... :/

What rims do you have on the car? Yeah a 215/75R15 is getting to be a pretty big tire on a G body. It is 3/4 of an inch taller and drop rpm at 60 mph by about 50 rpm. Are you going whitewall out?

Lifted & body mounts removed / replaced. Tomorrow, bolting these, and then preparing the car for the driver side :)

The car had a #5 body mount installed! Quite a surprise :)

Question: In this picture, you have all mounts unbolted on both sides and you are jacking under the rocker to insert new upper mounts? How is the number 5 replacement mount held in place (I saw no bolt)?

#5 is just placed into a hole in the frame. It is held in place by the weight of the body itself.

All four links are reinstalled, pretty soon the differential will make its way under the car.
