I have a unused 50" cleanup bucket for the XCHANGE system. My 2003 331D has been converted to hook and pin and my 24" has been converted. I was told that the original cleanup bucket was 40" and that the 50" is too heavy for the 331. I found a rental service that has a 40" but wants $300. and trade. Thats the same price to have the 50" converted. Is the 50" too heavy??
