Just wondering if anyone knows If there is a mount out there to be able to run a different style air conditioning pump in place of the stock 04 LS1 pump that I was told is not compatible with any of the air units on the market due to the fact the stock air conditioning pump on a C5 vette was either variable pressure or speed but either way it wont work & I would like to keep new pump in stock location along with alt, & power steering pump in there stock location's & not go to the Expensive billet syle mounts, Any info would be appreciated .
