Favorite mail order, car parts catalogs (NOT SUMMIT'S, OR JEGS...
I have a three year old Competition Products catalog... if I need something I drive there. I toss the Jegs and Summit catalogs.
Most of what Speedway sells is Chinese junk knock-offs... learned the hard way.
When I need hard parts I usually buy from my local engine or chassis shops... free freight and the same or better prices. Or I deal direct with the manufacturer...
