    I have sourced a set of Wilwood D52 caliper set up - https://www.wilwood.com/calipers/caliperprod?itemno=120-10937-rd

    And

    Pirate Jack tubular control arms - https://piratejack.net/chevelle-control-arms/

    The next piece i need is the spindle...

    I have been told that depending on the year, different spindles will have a different height. (i think it's post '73 spindles are taller).

    I am wondering if anyone has run into this issue and could provide some advice about what is the best spindle to use.

    They tell you to use stock spindles in the control arm description. Different spindles may be taller, but the ball joints may not be compatible (different taper)

    Both the upper and lower balljoints have a larger taper after 73.

    Do you need both upper and lower control arms or are you like me and wanted them?

    From experience, I can tell you the lowers are heavier than stock and the uppers are lighter. It is about a wash overall.

    I recommend you do not use 73 or later spindles. Use 72 and down disc spindles. If you want better handling, those arms add positive caster. I swapped ProForged tall upper ball joints into mine to get better geometry. However, if those are cheap Chinese ball joints, swap them for real Moog or risk one breaking like one did on me. Luckily I was going slow in a turn.

    Also, it says it drops the car 1.5-2" inches so be prepared for that or adjust up with the shims they also sell.

    Take a clue from me, put 90° grease fittings in the lower control arms. You won't be able to grease them once they are on the car if you don't.

    Last, when you get it aligned, don't allow them to give you positive camber and negative camber. New parts and new geometry require new style alignment specs. As much positive caster as they can make the same on both sides and at least a negative half degree of camber. It will handle like a new car.
