What do they normally go for??

That looks like a 1ton crossmember. This is the 1/2ton double hump xmember. You should be able to pic one up for $25-$50

Ok, yeah its from an 80 1 ton C30. So i am guessing i couldnt use the one i linked for my 87 R10? Was debating on switching out the crossmember for my dual exhaust setup or just using an s bend to work around.

Probably not, the trans will sit higher and the upper brackets wont fit because if I recall correctly, the frame is taller under the cab on 1tons. You could possibility modify it.

Man thanks for the info. I will pass and just let the exhaust shop work around the current one if i cant source one locally. What is the easiest way to tell them apart?

The ones like I posted are on pre 77(I think) 1/2tons and emission(catalytic converter) exempt 3/4tons into the 80's. It wouldnt hurt to have the pics in this thread handy when you find one.
