Help needed from the experts. I have removed and disassembled my Dana 30 axle out of my 1990 Comanche. I am in the process of installing 4:56 gears. During the disassembly I mutilated the oil baffle(slinger) behind the inner pinion bearing race and it is not usable and my install kit does not have a new one. This baffle is .015 thick and works in combination with shims to set the pinion depth. Can I just add .015 worth of extra shims or is it crucial that I install a new baffle?? Thanks
