Decision time: Do I bight the bullet and get an S10?

[gigamanx]

I had a good bit of time to work on the 49' 3100 this weekend only to uncover some big problems. The fuel tank is done for and so is everything associated with it. The brake lines need to be replaced and I need another front wheel cylinder. Finally, the new radiator doesn't fit because the 235ci I have doesn't have the short shaft water pump installed.

All in all I'm looking at $500-$600 in parts to get past these hurdles and onto whatever is next. I am realizing any money I put into mechanical stuff is getting wasted because I want to do an S10 frame swap in a year or so.

So do I bight the bullet now? If so, should I be searching for a rolling chassis or a complete S10 long bed truck? I've also read a blazer frame might be a better choice because it is boxed already.
