If not, they aren't all that difficult to make. The basic donor distributor is an early-1980's Chevy 2.8 Liter V6 item with centrifugal and vacuum advance. The housing, shaft, and drive gear have to be modified by some pretty precise machining. I made one a while back, using a new overseas-made clone of the GM distributor. If you do that, trash the foreign-made module and replace it with an OEM Delco-Remy item.
