. Yes, my Pro-Mod must use the center section from M/W's only, but my bracket car & my outlaw Superstock car can use a moser or strange. M/W's does theirs different, just so you can't use someone else's stuff that is much cheaper. I saw you were looking at a kit, so call them up and see what the same kit with 40's cost. They probably don't get a lot of guys with your weight and a clue buying kits, so they only posted the 35's??? Just looked up spools, 35's & 40's are same price?? So definitely give Strange & Moser a call. It can't hurt, and you are launching a lot of weight!!!! .
