does it make sense to start building the chassis before finalizing on a donor?

dave

you can make the base chassis and tahts it really, then once you have a donor, you can make the transmission tunnel, engine mounting place and other good bits

i would suggest, by experience, that you get the donor first, or you might end up having to modify stuff!

plus you won't have the garage full of chassis when you're trying to strip and recon things.

and the chassis won't get as rusty.

I got my donor 3 months after finishing my rolling chassis, it caused all kinds of grief - get your donor first, strip, clean and refurb, then bang the chassis together
