I'm the same way Henry (easily confused)!

The wrist pin fit varies but generally is a very close fit in the piston. On some, the wrist pin is actually slightly larger than the piston's wristpin hole (an "interference fit") so you need to temporarily shrink the pin by chilling it or expand the hole for the wristpin by heating the piston.

Someone else was recommending tie wraps. I use a "fancy" German ring compressor but most any ring compressor should work if you do it on the bench. Perhaps you can borrow one from one of your Chevy friends?

If you haven't put pistons in cylinders before I would recommend doing a few dry runs using the old rings. It will give you a chance to develop and refine a technique that works for you and if you break an old ring in the process there's no harm done. Dry runs are always quicker than waiting for replacements for broken rings.
