Re: Drop Spindle

Uncle,... it all has to do with the backspacing of the wheels you are running. Use a 3.5" BS and you will be fine. A 4" BS (like on a 15x8 ralley wheel) will require you to trim. Use a 4" or 4.5" electric grinder with a thin cut off wheel and you can do each side in about 15 minutes each. This is not a big deal. I've done this on every 67-87 I have owned for the past 25+ years. Just clean up the area left and right of the ball joint about 4 or 5 inches back. This is the "channel" looking part of the lower a-arm. (I wish I had a pic) Then bolt the wheels on and raise the truck with a jack under the a-arm,... and turn the wheels left and right to check for clearance.
