dilema:thoughts on a c20 converted to c10's worth

[s10blaster]

Hi everyone, I'm still on the hunt for a truck and have come across a c20 converted to a c10 (ie. suspension swapped out with a 70's c10) ...and has also been converted from a long bed to a short bed.

Does the fact its a c20 originally affect its worth or its resale value?
I've never owned a c10/classic chevy truck and don't want too many hassles if I ever have to sell in the future for any financial reasons etc.
Or does it make no difference? since its pretty much a c10 now anyway?

Thanks in advance for your opinions or thoughts. I know I overthink things but just am new to the whole classic truck thing.

Cheers.
