Do you also have an A-100? In that case, yeah, it's a pain to put in a bigger MC. We did a lot of grinding to clear room for the 1 1/8" aluminum MC, it's a lot longer compared to the single jug type.
It did bolt on no problem with the adapter (AndyF type), but there's not a lot of room around it like in most passenger cars.
Also, 1 1/4" MCs will not bolt on, diff bolt pattern.


"Hey mister, something's wrong with your car, it idles roughly" - number one comment I got in Israel when daily driving a 70 Barracuda with a lopey cam.
