I just bought a 95 Burb 5.7 and had to give it a good tune up, luckily, since I found 3 different types of spark plugs in there, one of them so old the gap had worn to .069, misfire found. Anyway, I broke some of the stock spark plug wire separators because it was 15 degrees out and they were old and brittle. So now I'm looking for replacements. I've eyeballed some of the aftermarket kits but the ones I have found are for old school heads, that you attach the brackets to the lower valve cover bolts. Obviously not going to work as is, since I have center bolt valve covers. Besides stock replacements, which I would be fine with, does anyone have a recommendation for an aftermarket set of wire holders?
