I wanted to keep my original wheel cylinders to the truck, so I decided to send mine off. I would rather have the original Delcos. I got mine from Vehicles of Victory, a source for military trucks located in WV. Tom sends them to someone else, so perhaps you could work something out. I am in the process of installing my brake system, so I can not vouch for operability. The machining and the fit and finish is real good though, plus I got MY cylinders back. Cost was still high, ~$90 per wheel but all wheel cylinders and master cylinder fit in a $12.44 USPS box. The new surface should make for a trouble free system whick will pay for itself in added labor/hassle. Going cheap usually means redoing sooner than wanted negating the value. Read too much about low quality reproduction cylinders.
