C10 vs c20 front crossmembers are they the same?

I want to section a crossmember for my c20 so I have it ready for when I swap the engine in a couple months. I can't find a definitive answer on if the c10 crossmembers are the same as a c20. I have access to a lot more c10 parts than c20. Anyone know for sure? I know the c20 uses larger u bolts on the lower arms but can I just drill those larger?

Lower shaft u-bolts aren't different. The upper shaft studs are 9/16" for C20/30 & 1/2" for C10's. The x-members will interchange but will require using the correct upper arms for the specific x-member.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

Can i just drill them out and run grade 8 bolts and put the 3/4 ton arms on when I swap them?
