Hope this is the right forum. Need help with a part number for a power brake booster. Seller claims it is for 1965-1970 Polara,Monaco,Fury,Newport,etc. Box shows part# 3004610 and written in marker on the box is # 2506833. My '65 parts catalog is a different #. My question is did this supercede the original number and will it be the proper booster for my '65 Monaco? Thanks for the help.
