I need to rebuild/replace the calipers on my 72 e3 as one is leaking. It's the first brake work i've done on it and noticed the front has vented discs on it. I am planning on rebuilding the calipers but for a short term fix to get it back on the road I want to pick up a new set of calipers to swap. Anyone know what calipers I should buy to support the wider vented rotors on it?
