big brake kit on MustangII clip

i have a question regarding the 13" big brake kit M2WBK-D13G.

will the spindles supplied with the kit interchange with a Heidt's MustangII 2" drop spindle?

Good Morning,

Yes, these will interchange or you can buy the wheel kit only and use your Heidts MII spindles.

thanks, i called and talked to Jeff... kit is waiting on will-call.

another question... is this an aluminum caliper or is it cast iron?

Thanks

Good Morning,

They use the big 2 piston (52mm) GM Iron C-15 calipers.
