You will have to ask Niner he is the track cutting expert, hell he might cut one for ya for a small fee. He invested in the proper blade for his saw and he did stretch it out but I recall that the hardest part is turning the track inside out.
Dug the tread out for my B.C buddy, anyone thinking of a 3" check it out!
Ya my buddies M8 was spanking everything on the hill so I think ya might turn it, go for broke and do the 174 you wont regret it.
