Title: Aftermarket transmission crossmember
Post by: BradRuiz 83 on November 21, 2019, 07:33:46 am
I am missing the transmission crossmember on a recent k10 I just purchased... does anyone know if I can use a aftermarket crossmember, and if so which one would be best...

K10 isn't enough info. What year, what transmission, what transfer case? etc

So what is holding it up now? Obviously someone swapped it in since it's not stock. I would suggest just getting a stock one and after you position it, drill the holes appropriately.

You might need to do a cut and shut with your exhaust as well which is what I had to do when I swapped the TH400 in place of the TH350.

I've seen a couple of aftermarket cross-members for 2WD trucks, and they are usually used to give more space for dual exhaust.  I think a vendor on Summit offers one, and there is a place in Texas that builds them.  However, I've not found one for a 4WD truck.   

There was also a factory dual exhaust option in the 70's, which may have had a W-shaped crossmember with more space, but I've never seen one to check it out.  With a stock crossmember and NP203 my '75 has plenty of space on one side for the exhaust, but barely enough space to fit a 2" exhaust pipe on the other side.  I have to keep the exhaust hangars really tight so the pipe doesn't bounce up against the crossmember when going over bumps.
