If it where my car, I would build a full frame, complete IRS and IFS swap, coat the underbody, cut out floors and raise them and a couple other odd's and ends.
Yeah their the toyota calipers, I am still baffled to this day, what happened, I was only leaning on the window with one hand, while sanding with the other and it cracked.
alright, rebuilt a set of the brake calipers that will be going on my car, the other set is available for sale as is, or for more money, I can clean and rebuild them.
