Improved design 1962-1974 Corvette distributor cross shaft tachometer drive gear and coupler. A common failure on original tach drive distributors is the cross shaft gear becoming stripped. Is the problem issues with tachometer cable routing, binding up the gear within the coupler or is it a gear with excessive end play causing the teeth to misalign? Either way, the engineers at High Tech Innovations developed a cross shaft gear and coupler assembly that helps eliminate these problems. The Dura-Last cross gear assembly assembly features a stainless drive gear with a larger "bearing" surface matched to a stainless steel coupler with needle bearings to eliminate binding and wear over a longer period. The improved design will certainly extend the life your tach drive distributor.

Almost no effort. Either snap on or plug and play. Probably no tools involved.
Simple installation with common tools. Probably less than 20 minutes for installation. Easy enough for
anyone who can read and follow instructions. A good first project for someone with no experience. Hard
to mess up.
A little mechanical experience is helpful but not necessary. Possibly a good first project for those with
a little more confidence. Will probably take more time (20-60 minutes) than #2.
Mechanical experience a definite plus. Not a good first project for the inexperienced. Most likely a 2-3
hour job minimum.
Only for the experienced wrench. Most likely requires good tool collection, possibly special tools and
a fair amount of experience. 95% of people will choose to have this installed by Zip or a professional.
