I take it this is a 2wd? Do you ever get through OKC? Or anyone of your family or friends? I've got plenty of those 2wd Auto Trans crossmembers. They should be the same for Th350 and 700r4 and for Th400 and 3/4 ton trucks too for that matter. It would take me a bit to get it since it's out at my dads, but I have 1 if you need it.

Correct. It is. Thanks for the offer, but I think I will just go aftermarket (just for the fact that ls swap in the future.)

Wheather you have to drill holes or not depends on whose motor mounts you are using but it's not too hard to drill new holes if you need to. If someone had a th350 in it at one time and you go with the 4l60E and Tejas mounts I think it works out that the mounts slide the motor forward enough to where if you had the th350 the 4l60E now bolts in it's place, but it sounds like you will already have multiple holes in it, so you might just check the furthest forward set of holes. If you have 4 sets of holes and still need to drill some you might want to either weld up the old holes or lay some 1/8 plate on the top side of the bottom rail just to help offset the missing metal. Might be overkill though.

Im not swapping at this time. I am only replacing the "oem" one since it is mangled and wasnt bolted correctly. So it was a 305/350 truck. It has a 1973 350 and a 700r4 whose rebuild date, if thats the date written in tamper proof marker, was 2014. But ***** not right with it.

Whats going in is an 87+ TBI motor with a carb intake and having the 700r4 rebuilt and put back in.

This is what my transmission cross member looks like. I dont know how it was supposed to be bolted but I marked up how it was bolted and I pulled off. And note, this one is at least 3x better looking than mine.

This may be a shade off topic, I'm converting my K10 from a 700R4 to a NP 833. Initially I'm wondering if the same crossmember will work, secondly the bolts and nuts are rusted to ****, worst case senario I may need a new crossmember all together.

As far as I know they all use the same mount to the crossmember so it should. On squareup.com they have a list of compatible transmissions.

Nuts and bolts are easily replaced. Check out the crossmember and if it is in good shape then that is all you need to do.

The main thing is knowing the trans will hook up to it. I appreciate the info.

I'm usually upbeat about a product that is affordable and works but anything made by transdapt I will pass on as a matter of principal because I have been burned by their parts more than once, either in a failure or not fitting the application it was listed for.
