Trans shield

For the guys that cut access holes into the firewall, are you using a stock k-member or an aftermarket one?

The reason I ask is because I've read that the QA1 (and maybe others too) k-member moves the engine forward about 1" from the stock location. I'm wondering if that extra space will give me enough room to install the shield without cutting.

My drivetrain is out of the car now, so I might as well tackle it.
1975 Duster originally a 318 car, has a 440 in it with motor mounts. If QA1 would move the engine forward an inch that may help, but that may also not be the best for weight transfer. The reason the bell bolts are such a pain is with the CSR shield you add the thickness of the shield, plus there's a flat metal bracket for extra strength that goes from the top bolt to the 2nd bolt down on each side. I don't know what the thickness of both are offhand, but with both probably adding close to 1/2" so that just makes it pretty much impossible to get a wrench on the bolts.
