Hi All: Can/will anybody tell me what brand/model valve spring compressor would work on an early MC engine. I know some of you McGyver types have built your own. I just want to buy one ready made that works. TIA as always, Mark Pollan, '86 5KCSTQ 268K Miles P.S. I have a Snap-On catalog in my hands so if one of those works I'd love to know the number.
