MSD-8464 Bushing & Spring Set, MSD Distributor The kit contains an assortment of springs and advance limit bushings. Features: Fits all Billet and Pro-Billet MSD Distributors The MSD Distributor Advance Kits are the same kits that come with your MSD Distributor. these are listed as new other. I bought these for my corvette small block. upon fitting it was clear that they had already been changed so this isn't required. I swapped out the light blue bush with the new one and on comparison to the kit it's identical, but I'd already built it back up so I just replaced the new one with my light blue one and popped out back in the bag. grab a bargain and no international postage as I'm in the UK.
