I support lots of parts suppliers/vendors when buying for my HotRods, StreetRods, RatRods and Race Cars.
Quality comes before price in my book and "Made in the USA" is always my first choice,,, with that said some times the "best USA stuff is not available"
and yes you will find some (very few) but some "Import Parts" on my stuff.
Yes I use Speedway, Jegs, Summit Racing, for misc items.
and thus far have had good luck and excellent service from all 3... Speedway has more variety for the HotRods and older stuff.
Keep the Car Hobby alive,,,, Buy, Build, Drive and Race..... Support your local shops and vendors too !!!
