As far as I've seen, all those RAD quick hitches fit each other. I've seen Bs with BX blowers, Massey GCs with BX blowers, Bs with L snow plows, etc. As far as price goes, I've seen a couple of the smallest sweepers (48 0r 54" ??) in nice shape on CL for around $1200 ish (no quick hitch included)..... so the price of that one seems reasonable if it isn't all warped from a fire, etc. If it were me I'd have to factor in the cost of adding the hydraulic angle though.
