Factory tach W/ new tach internals??
Has anyone put new tach internals into a factory type tach? I can not get my factory type tach to work with my MSD box (yes I have the correct filter).
I really want to keep my factory type gauges & my MSD system!! But, I have to have a correctly working tach too. Right now the tach registers more RPMs than the engine is turning and increases disproportionately...
At this point the only solution is new tach internals in my old tach...
So, who has tried it and did it work?
