z-bar length question

I’m digging up this thread. Saw It when using the search button. Now that I’m close to
My 4 speed swap... I’m realizing all the wrong stuff sent to me from classifieds online. I think it was honest mistakes. But I have an 8” Z bar. Well... upon research... that’s a slant six bar. It’s 1” longer. Can I just lop off an inch on the bell side and get away with it ? Or do I need to buy a V8 z bar? Thanks.
