Good kit

July 16, 2016
The directions are bad, or I'm just stupid. The directions say to scribe a line and grind away the spindle to make the caliper fit, no mention of which way the bracket goes, I ended up grinding away on a brand new set of spindles (around the top of the king pin) only to realize I needed to flip the bracket around cause I had it on backwards and needed to grind away on the center section more towards the center.
No, I would not recommend this product.

This is just what I needed for my 1930 model A, but needed some adjustments on one plate, and to fit the calipers from a 74 Chevy, I opened the ends by 100 thousands on each plate (50 thousands each side).
Pros:
  • Great product
Cons:
  • if you have to adjust then remember to paint.
Yes, I recommend this product.

Will this bracket work with the calipers and rotor from your 91031909 kit? I bought that kit for the rotor bolt pattern but I would like to use this bracket instead of the one supplied.

Part number 91631903 This basic kit is designed to be used with the early 69-77 midsize caliper and 11” rotors. The 5 ½” bolt pattern kit number 91031909 uses an 11 ¾” rotor and the early Impala calipers. Parts will not interchange and work properly without extensive modification and machine work.
