When you guys do your frames do you typically keep them the same width the whole way ,or taper the front ? this would be for my rr truck im about to start on,Itl have a chevy 250/3spd man, suicide front axle setup,buggie spring rear and about a 48 to 50 inch bed.And if anyone knows where i can get a front spring perch for a 2in spring that will mount to a square crossmember id appreciate that.Thanks
