I am looking to upgrade the ignition system in my 620/l18 to a matchbox dizzy. I read the stuff on here and the jason gray thing, and I was wondering if a remanufactered distributor from rockauto for a 1979 l20b would do the trick (it's only a little more pricey than a JY part, due to the wholesale thing going on). If it's good to go, is there anything else I will need to do the swap? Also, because it's going in an l18 do I need to modify anything on the motor to fit the dizzy, or is there an aftermarket bracket available (couldn't find anything)?
Here is a link to the part; it's the cheapest one:
