set the firewall back 3 inches. and set up the motor plate. and changed my mind on the axle location. so i moved it forward 3 inches ..
im almost 100% that its a dodge 100 axle id like to figure out what i can do to run disc brakes on it .any info would be great .
The 57 looks great. I just found this info for you regarding disc brakes. May be possible to use 1999 300 rotors on the original hubs with midsize gm calipers. You'll have to make the caliper mounting bracket for the calipers . The hub register hole for the 300 rotor is VERY close, if not identical to the early hub. With the right studs and a little machine work, you can swedge the rotors to the hubs using right hand threaded studs on both frt hubs. Or you can buy a conversion kit here ( seems a little expensive...) www.scarebird.com Good luck and have fun with the build.
