Seller's Description
Extra long BSA Sump Plate Studs (Set of 4), ideal for BSA 'B & M' series; Gold Star, B31, B33, M20, M21, C11G and C12 models. These studs fit the thicker aftermarket finned alloy sump plates used on the above models. They will also fit rocker covers, but are longer than normal.
Includes 4 x 1/4" reduced hexagon nuts and 4 reduced diameter washers. If spring washers are more desirable, I can replace the washers with four spring washers, just let me know at checkout.
item number 290636546091 - 1" long. These are for use with aftermarket alloy sump plates for 'A' models (finned alloy sump plates). And are also 67-280 rocker cover studs.
Bright Zinc plated, best high quality around!
Made in England, all our nuts and bolts are British Made.
If you purchase multiple items, we will weigh the items and offer a postage discount accordingly.
