I was just looking one day how to build up passenger side of slant 6 kmember like a V8 one and realized that the truck mount looks like the 4" raised portion I need..low and behold it was perfect ..I had bout half the town installing 340's in Granny's Dart..and nothing hooks better on the street like 6 cylinder springs and torsion bars...bulletproof the rear and tie the frame together..holy **** 10.90 potential..dont forget those 9" front brakes..lmao.....
