I got a Keyster (from Canada I think). Had all I needed for a 68 1 bbl. quality was ok and had most things that needed updated/replaced.
Depending on your year there might be some OEM kits available??? Would not hurt to give it a try. I have used NAPA for tons of stuff over the years and rarely if ever, I had a problem. Good thing about them is that they are close by.
I've purchased non-oem stuff from Man-a-fre, sor and others and their customer service was great and the part may have "done the job", OEM is the way to go.
