The crossmember that has the slot on one side fits all configurations, the only thing you want to confirm is the height, 1 ton is flatter than the 1/2 and 3/4 ton.Kenny, the key is that it had to have a TH400 in front of it! If that x-member shown definitely had a TH400 it should work. The part numbers between TH350 & TH400 are definitely different.
Yes
Ok now we're getting somewhere.So more research tells me I'm asking for the wrong thing!!! So sorry guys! I need a x-member from a 79-84 K30! Everything we are doing to my bosses truck is based off of a CUCV. So after getting to work I thought after all this confusion that I better check my CUCV catalog. Sure enough, the part number for the x-member I pictured is the same as civilian 79-84 K30. I will change the title to thread... Thanks for all of the help.
