Engine cross member pics please
 
Pulled the engine cross member off my frame and didn’t take pictures. Now I’m having trouble with clearances. Does anyone have any good shots of a 1970 k10 cross member installed I think mine is on backwards.

Nice pictures, thanks. Is there an offset in the cross member, meaning if I were to mount the crossmember, not the perches would it push the motor either forward or backward. It’s hard to tell from the pictures and I can’t tell on my truck because the motor is in. I put a stock set of valve covers on and was able to get the cab mounted but the valve cover is within a half inch of the firewall. I don’t remember it being that close before I took it apart.

Sorry, my post might be a little confusing. I meant to say if you were to put the crossmember in opposite of the way it was originally installed would it push the motor back.

Only specific offset cross-member I know of is for the 292 L6 in K/ frames. The fuel pump and motor mount trade positions between the 230/250 and the 292.
The 292 L6 is a tall block and develops a lot of torque, so they moved the RH mount forward to counteract it. On a 2WD [C/-] frame the mounts hit the frame OK, but the 4WD frames are wider, so a diagonal X-member is used on this engine only. If your truck came with a 292 originally, you might have holes in the wrong spots for a V8.
V8s have symmetrical motormounts, unless I'm wrong.
