Can anyone tell me if the crossmember on a 72 K20 is the same as on a 72 K10?

Its almost time for a new motor....

thanks, James

Same overall... the only differences you have to look for is if the donor or what you have was a 292 engine... the top part of the mount is different only on the 292 engine.. so a 250 six cyl mount will be the same as a 350 or 307.... the only odd ball is the 292 engine mount. Oh,... and no difference between K10 and K20.
