4l65 crossmember first gen

[Ishmael]

I can't things to line up with my ls2/4l65 combo. I ordered a 700r4 crossmember from CPP mostly because a lot of the crossmembers on summit's site listed them as working with a 4l60 or 700r4 in a camaro. I bought hooker plates that put the bellhousing in the stock location. However, the mounting pad on the trans goes at least 1.75 inches past the crossmember holes and the crossmember holes are off center. So I have a bunch of questions.
Is the 700r4 the same length to the pad as a 4l65?
Is the pad on the 700r4 supposed to be off center or did CPP make another POS?
What mounts and crossmember did you guys use on your swap? I currently have hooker plates.
thanks

Are you still dealing with this or are you past it now. I ran into a similar situation and found there are several different lengths of 700R4/4L60/4L60E transmissions. Send me a Pm and I'll email you a file I put together on the different lengths from bellhousing to mounting pad and bellhousing to overall length.

Jay, you should post that file up here as someone will no doubt be looking for that info later on.
I ended up having an extension added to the frame mounting tabs. Then I found out that even when it was far enough back the engine was hitting the firewall so I had to buy new plates anyway. A smoothed firewall would have worked and looked better but ah well. So I get the new plates and the trans mounting pad is still off center but, four new slots in the tabs and maybe I'll be able to make it work. I still don't buy CPPs story. It may be true but every factory piece I have ever seen has the pad centered.
Should have gone with an adjustable crossmember to begin with but I just didn't find anything that looked strong while still offering clearance that would work with the new 4l60s. I know there are some out there but they looked weak and like a hassel. I guess I should have made my own from a th400 crossmember. I still don't buy CPPs story. It may be true but every factory piece I have ever seen has the pad centered.

I know how frustrating it can get when 'bolt-ons' don't bolt-on. I ran into a problem on my camaro putting an LS1-style 4L70E behind my Gen1 sbc. I don't see how to attach a file but will look into how to do it. My problem compounded when I tried to relocate the torque arm mount to the crossmember so both the trans didn't line up and my torque arm didn't either. It was a mess.
