Car is 69 GTX, 440, Edlebrock heads, with air grabber (N96). Will a MSD Pro Billet Distributer, # 8387 fit? It is about 1/2 inch longer than MP elec dist. Thanks

i don't know about a 69 B body.
i have a 72 road runner with a air grabber hood, have 572 hemi on the stock K member with shumacher conversion mounts. the only distributor that would fit was a stock mopar one. the MSD one hit the air cleaner base. i had to modify the base to fit the hood but couldn't modify it to clear the distributor to clear the air filter.

The MSD will hit the rubber and some of the fiberglass part of the AGrabr. The Mallory will also fit along with the Mopar one. You can also recurve the Mallory easy enough, and they sell springs for it as well. I have since went to the Mopar one when I found someone that does a great job of recurving them. It just looks better without that big red cap that the MSD has. The Mallory one I painted tan.
