Looking for 8mm retainer that mounts to the valve cover studs 2 four wire holders and 2 two wire holders.
If you find any of the 2 wire retainers, consider yourself lucky. They're like hen's teeth! It's a shame none of the repro places have done them yet since they're the correct ones.
I have some 4 wire - used & NOS - for factory 7mm plug wires. Also have a few hens teeth, (2 & 3 wire) but, not available at this time. I think 3 wire looms were used on 350" motors
