    So what does everyone think about this idea? I have a chevy 6 inch drop axle. I got a sleeve and spacer made so the axle end is the same size as my plymouth end. Any reason I shouldn't install my plymouth spindle on this ? 20250624_171827.jpg

    Are the spindle centerline distances the same between the 2 axles?
     
  3. If the camber angles are the same you’re good
    But using a gm spindle and changing the bolt pattern isn’t difficult

    Yes, extremely close.

    I was going to go all gm but I wasn't sure about the steering arm. Figured I get the sleeves made by a friend for free and at least give it a try. Trying to save money where I can.

    I got my front end mocked up. I need to weld the leaf spring pads to the axle still. My king pins fit great. I pulled the 2nd and 4th leaf from the bottom and dropped the motor in to get an idea of ride height. Chevy 6 inch drop axle sleeved for plymouth spindle.

    It looks like it's camera angle, but that looks like the top of the tire is kicked out. Of course, the top of the engine looks kicked out the other way, so that's why I started with that.

    I just went and checked with my super sophisticated method. Is this good enough? I would assume it is but then again im learning as i go from all of you. 20250629_191820.jpg

    Good enough for a roller! :p
    I kind of figured it was close, but the pic didn't help.
    If anyone is annoyed by a tenth of a degree, they can chip in for the axle bend at the alignment shop! :D

  9. They will kick out some without all the weight.
