Crap did I say Trail-Gear, I meant All-Pro

All-Pro is pretty much the same as Marlin's old spring swap not Trail-Gear, only thing I could think of with your other issue is that the Trail Gear SAS is probably not designed to be used with the military wrap style springs. The hanger mounts probably have less clearance and can't clear the extra spring wrap.
