No real update, but instead of using the McGaughy big brake kit that I already have, I bought Wilwood 140-10776-d 6 piston front kit, Wilwood 140-10093-d 4 piston rear kit, CPP modular 2 inch drop spindle. I guess I'll put the McGaughy kits back on my GMC.
I may be able to finally answer Keith's (Lolife99) question about how the track width is affected by different spindles. I will have a set of stock 70 drum spindles, 72 disc spindles, 73 up spindles, McGaughy big brake spindles, 73 up McGaughy HD drop spindles, CPP new style (modular ???) HD drop spindles, and finally the modular drop spindles. I will probably just mock up a jig to do my measurements...damn installing & removing all these different spindles on a truck
