I bought them at The Southeastern Bug Fair in Toccoa GA.(swap meet). Carbs(45 DRLA's), intakes, linkage and 2 CB master rebuild kits for $200. Had to order a throttle stop arm and return spring for the right side.
I just tried to put the spring and arm on and CB sent me the wrong spring. I just emailed them to see if they will send me the right one.
