This is a serious question, so no debates please.

Looking at a coupe, but it's a gasser

Are there any differences in the bodies between a W123 diesel coupe vs. W123 gasser coupe ?

I am NOT looking into converting it to a diesel. I appreciate the wiring harness is different and I would probably need to swap out the steering column or at least the upper half.

My question pertains to the bodies and suspension: Are they the same? So, if I had a bunch of extra parts, would they exchange right in without issues, e.g., differential, front suspension parts, maintenance items, et cet.

Thanks in advance,
