Title pretty much says it all. I was thinking I could have someone weld the 68-69 shock mounts to a 67 diff. The upper shock mounts are the same right? It should be do able don't you think? I was even thinking of getting a '68-69 diff and throw it in (after a rebuild).

I asked the same question here many months ago. First, the rears are interchangeable between 67-79. The lower shock mount is actually on a separate plate that bolts under the spring (check out a parts catalog or assembly manual, or look under your car).

So you are asking, "why can't I just get a 68-69 driver side lower mount?"

The problem is the upper mount, which was completely redesigned in 68. The location and angle of the upper mount and reinforcements is different. The consensus was that it would be too difficult to change. Fix wheel hop a different way, such as with fiberglass springs and better shocks.

The easiest way to do what you are asking about is to install a cross piece that is sold that will allow changing the upper mount of one of your shocks. Then use the matching lower bracket. IMHO. pdq67

Where do I get one of them cross pieces?

67Stock, If I remember right, Competition Engineering sells the cross member. It's welded in between the frame rails. Do a search on "relocate" under the suspension forum, I think that may help. If I recall, there was discussion that using that particular coversion kit may cause you problems with your exhaust system routing the pipes. Good luck.

My 67 had multi leafs with Ansen Ground Grabbers and a lot of wheel hop. I decided to convert to urethane bushings and lose the traction bars. When I ordered two leaf spring mounting plates from Year One they sent me a pair of passenger side plates so I decided to try out a staggered setup. It mounted the passenger side shock in the stock location and the drivers side behind the rear end. I think this is the opposite of a 68 setup.

I did a real half *** job and just drilled a hole in the body for the shock stud and bolted it in. I didn't even bother to use the upper shock mount plate. Wheel hop disappeared completely. Is there a reason no one else is doing this? It seemed real easy... too easy.

Well you don't exactly wanna just bolt the shock to the body cause it could bend and tear that sheet metal right out. That's why it's reinforced with a mount.

But yeah my whole reasoning is I either need a bar hooking the diff to the frame (GM did it for high performance engines in '67) or staggered shocks like the 68's and 69's got.

I wouldn't mind moving the shocks in on the other side of the leafs either.

If someone could send me a pic if they got a crossbar between the frame rails with the shocks mounted to it I would appreciate it. I'd like to go this route but am having a hard time picturing how I'm gonna tighten down the shocks. Very carefully I guess...
