Moving differential back problem

[SavannahZ]

Hey all,

I am in the process of moving my diff back into the later corrected position. The problem I'm having is that the front crossmember will not line up. I have the curved rear tranverse(?) mount and the later moustache bar. Am I supposed to be using a later mount insulator? I have the 1970-1971 model. Am I supposed to turn it around? There is a very minimal difference if I do.

The other option is just to pry it and jack it into place????

Help!

I'm not sure if I follow, but the problem I had was with the strap being too far forward. On my first strap I just jacked the diff up into it and that worked OK but eventually the strap started to tear. At this point I took the strap mounts off and moved them back a hole so that they were only held in place by the rearmost hole in the body. I had to grind a little lip off in order to do this, that part will be pretty self explanatory when you look at it. I drove it like this for a couple years more, autoxing, track days, and daily driver. Now I've finally decided to do a front diff mount that doesn't require a strap at all. There are some very good ideas here if you search you'll find them. I like the clamshell or angle iron designs, would have done one of those if I had seen it first. Instead I ended up with the Simon de Groot method (probably got the name wrong on that, sorry) which is good, but more difficult and requires a lot more fabrication.

Thanks for the quick reply. I solved it. I remember reading somewhere, that I should reverse my mount insulator. When I measure it, it was like a quater inch...which wasn't far enough to move my crossmember into alignment. So, I held my old one in reverse up to the installed one and it was inch difference. Turned it around and YESSSSS it all fits like a dream!

I wrestled with that damn thing for two hours. Sometimes you just have to stand back, relax, and think.

Thanks again!
