I have a 63 Polara that had a front disc brake conversion installed, but nobody knows what kit was put on it. Without taking thigs apart I can see that the caliper bracket on passenger side has part #2627BL cast onto it. Is that enough for somebody to know what parts were used in the swap so that I can look up correct caliper and pads or do I have to tear it down further. Attached is a pic Also what might cause fluid level in front of master cylinder to go all the way to the top when it was only filled to about 1/4 below top? Thanks!
