Any input Gear Vendor Over drive with 18 spline 833

Anyone installed a G/V in a 64 with a 18 spline 833? Did you have to "clearance" the tunnel? What were the results? Thanks

Guess no one uses the Gear Vendor overdrive ?

That's one of my future upgrades when I put my car together. Cheaper, and really very little hassle to install, and has a pretty good following from what I see.
