i put them on my ram k and i had to make a bushing to cover the different size of our linkage to the carter / edel carb. took a rum, tounded with dremel, smoothed holes, viola, perfect spacer. repaet. i used aftermarket cleaners due to the cost repalcement if mine are stolen. and finally, i Hope you are saying 500 for both carbs new. BOTH. if not contact me i will give you number of summit racing. or, here,m save you a trip, 1-800-230-3030 _www.summitracing.com_ (http://www.summitracing.com) ps, you wont regret it. put your original ones away so you dont have to spend an obscene amount to replace due to acts of god. my two cents. tim pps, the base bolts right up. the carbs have 8 mounting holes unlike the standard four. no problems........
