If you own a GM vehicle that is equipped with a manual transmission and you want to eliminate some of the binding in the stock clutch linkage, then purchase from Chevrolet #3887177 fork for the Corvette.
This fork fits all GM bell housings, (Chevy II, and Vega/Monza don’t count, along with anything built after ’82) A new lower pushrod must be manufactured using either a Mr.Gasket 2477, or two spherical rod ends as I did.
If you go the rod end route, the pushrod end of the fork must be ground out to allow the width of the rod end to fit between the ears. The advantage of all this is that the lower pushrod cannot fall out, and has a real pivot point instead of the funky stock stuff.
Just like those GM guys…save the good stuff for the ‘Vette.
Autotronic Controls Corporation If you are going to install a DIS-4 ignition amplifier on a 97-99 4.6L Mustang then you need to know the following. In order for the unit to function correctly on Ford’s distributorless ignition system two 2-channel tach signal amplifiers must be purchased.
The part number for these is 8912, which is NOT in the 99 catalog. Also, there is a wiring harness that plugs into the DIS-4 that allows you to splice in the tach amplifiers without chopping up the original DIS-4 harness.
I know it all sounds like a wiring mess, but it isn’t too difficult. If anyone is doing this upgrade I have harnesses available Free of Charge.
