Having an interestingly difficult time nailing down a source for a complete o-ring kit to reseal all my hoses. Right now, I'm just putting it back intact so it won't bet crud in the system. Tried Napa, tried amazon, tried the classic parts houses that sell a kit for '69-'70 chevelles.....which may be the same kit??? This should be way easier, just looking for a source.

Unless things have changed, just buy any kit with a variety of green o-rings and you have all you need. It’s a small bag of parts, will have plenty of each size, and won’t be that expensive.
