Hey my87Z,

This one is an '84 Z28. I believe the T-Top models weight more due to extra reinforcement.

(of coarse my motor makes almost 500tq) but i learned my lesson and bought a complete 33 spline 12 bolt from moser (32-3300 to my door $$$)
Completely forgot about the dreaded rearend . I still need to check and see if it is the stock one (got the car a couple years and haven't touched it since). $3300 is way out of the price range for now. This may just send me back to drawing board.

That should get me started in the right direction.

Build mounts off a 9'' or 12 bolt or Dana rear. Get the front mount off the trans.(You will only break trans mounts like this) and attach it to the trans x member. Dont screw up the pinion angle. BTW, for those with a more streetable car you can use the tailshaft from a vega to attach the torque arm to a TH350. They were torque arm also.
Good to have a recommendation on the TH-350. Thats two votes to ouster the 7.5" rearend. Thats good info on the mounts and torque arm. Glad you brought 'em up.

I don't remeber the tire size on the slicks on hand. I don't think the car is tubed.

4.11 would be ideal?

Not to go completely off-topic with this post, but, and I know what I'm about to bring up is nothing more than a temporary fix, at least behind the 454, how about a 4th gen rearend swap? I do have a rearend from a '95 Firebird, an Eaton posi, 4.10 gears and Strange axles. With some minor strength fixes, I imagine this setup would be fine behind a mild 350 with a TH350 setup, if not a big block. Any thoughts?
