FS: Used MSD Tach Adapter PN 8920. SPF to TC
I used this is in my car for all of 1 month before I cam across a tach that worked without the adapter. The adapter works well, and is needed when running an MSD box with a stock 914-4 tachometer.
SummitRacing.com sells them for $65 new, so I think $35 shipped is a fair price.

Thanks for looking,

Bump for price reduction $25 shipped CONUS
