59 GMC Old 4 speed to New 4 Speed

[rwolf]

I have a 59 GMC that originaly had a 336 in it and I am going to be switching out my stock 4 speed to a super t-10 when my 421 gets done, but my issue is how can I set a third member to support the new and longer tranny. The location of the newer brake booster and mount is right at the location where the third member will be to mount to my new tranny. Any ideas
Thanks

Ill take a guess and say the bottom of the trans will be just about lever or alitle below the frame rail so you should be able to get away with a 2" drop aftermarket trans member, which should give you the clearence you need.

That is what I thought I could use but the original mounting bracket for the brake master cyclinder sets right at the location were the crossmember would not to attach to frame rail and my new power master cylunder uses the original mounting plate as well.

mount the brackets on the bottom of the framerail i belive it should be enough room for ya
