1872 Qa 42 thrower
 

Ihave never owned a super, but looking at an 1872 will the old QA 42A fit on the 1872 or do I have to get a 450 ?

I don't know if a 42 will be wide enough my 1872 is 44 in wide but I can't remember if that was with stock 8.5 rims or my 10.5 rims but personally I like the 450 2 stage better my self.
