I have 2 W350 5 spd SRW trucks and want to make one of them into a dual wheel 4 wheel drive. I neighbor has a D350 auto that he may part out and I want to end up with a 4WD dually. The gear ratios are the same but my question is will the front ends align properly? Is the 4WD front end different between the SRW and the Dual rear wheel? Thanks for your input.
