I want to notify bolters in the Austin, San Antonio are of an excellant source for parts. Texas Undercar Parts has two outlets in Austin. They have at least one, probably nore,in San Antonio. I have been surprised at the inventory of parts they have for my 1960 1/2 ton but they are not exclusive to Chevies. They stock for both old and new, and their prices are very good. For instance, new rear wheel cylinders for my truck were $8.07 before tax, and front wheel cylinder kits were under $4.00.
I have no idea what all they do stock, but reccommend them highly.
