I gutted my precats while they were on the car. I can't imagine trying to get those suckers off without dropping the transmission. It is a super tight fit. This was posted yesterday with good details about ease of dropping the tranny:
You can get the pass side off and on with a few curse words, but it's super difficult to reach the drivers side. You'd have to take the brake booster and a bunch of stuff out and work from the top.
If I would have known addiction was this expensive I would have seen a shrink a long time ago. --BadZCar (FL)
