I have a 1959 4bbl Carter carburetor 2840S for sale. It is listed for Invicta, Electra and Electra 225 (all 401 ci) but it will fit a 1958 as well. I bought it for my 1958 but a few weeks later found a original 1958 one, so the 1959 one is for sale now. The carburetor was completely disassembled and cleaned and was assembled with an Ethanol resistant kit to deal with our modern gas. It comes complete with the starter switch on the carb. PM or email me for more or larger pictures. I paid $250 for the carb and $50 for the kit, but I am willing to sell it for $200. Chris
Sorry guys, but the carburetor sold last Sunday on ebay. There are currently two more listed (not mine!): http://www.ebay.com/itm/1959-60-BUI...Parts_Accessories&hash=item4d04138915&vxp=mtr http://www.ebay.com/itm/Buick-61-re...Parts_Accessories&hash=item4ab7f09b50&vxp=mtr Chris
