I finished putting my BWt-5 in my 71 last night . I thought I would share my install ideas as far as tranny crossmember and mount.

The mount seems to be the same regardless of what tranny you have . I have the auto and the 4speed and the BW and they were all the same. The crossmembers are different though.I had two early crossmembers ,one from a 4 speed and one from my auto. The auto was much lighter and actually had an offset to it,which I needed since the trans didn't line up. I decided to grind a relief hole on the forward side of the mount so I could slide it forward on the trans. I cut off the ears of the mount and rewelded them rearward (3/4") to put them back in proper place to line up with trans. Then all I had to do was elongate the mount holes in the crossmember one hole width for it to line up properly.

I thought it was interesting that the original automatic trans crossmember had a shim to raise the tranny about an 1/16". I had to use that shim to get the bwt-5 to line up perfect with the diff. Hope this helps someone thinking about this project and I hope the pics upload

Thanks for the pics, Steve! Looks good.

I am wondering if you have installed the shifter yet, and if you had to modify the trans tunnel at all.

I should have titled this thread BWt-5 install in a first gen but I don't know how to change it now.

Hopefully someone will find it using the search button.:classic:
