I've been lurking off/on for a while now and am finally ready to start working my frame.
I've got a 53 chevy frame that I will be swapping out the front crossmember to a GMC and installing a mustang II. The swap is pretty straight forward, but my question is regarding riveting, bolting or welding it in place (GMC crossmember). All the researching i've done recommends riveting and not to weld. What I haven't come across is any info regarding the installation of a IFS crossember and if this has any impact on the necessity of riveting/bolting the front crossmember instead of welding. My non-engineering mind is thinking that the frame flex/stress that the original crossmember would see w/rivets isn't as much since the mustang crossmember/boxing plate will make the front frame much more rigid, not to mention that the engine will no longer be supported by the original crossmember.
Anyone have any thoughts/input?
