Tremec TKO 600 Transmission - Clutched And Dangerous Part 2

While test-fitting the driveshaft, it's good practice to check for sufficient runout. The sweet spot is roughly an inch, which prevents both the slip yoke from smashing into the trans as the suspension compresses, and ensures adequate spline engagement.

With the pedals in place, the steering column was re-installed. Obviously, the granny column shifter is of little use now, so it was tossed in the trash.

After installing the clutch linkage and patch panel, the final step was buttoning up the interior. The only modification necessary was cutting a small hole in the carpet for the shifter. If retaining the bench seats, one caveat is that the shifter needs to be positioned as far forward as possible. Fortunately, the TKO 600 has multiple shifter mounting locations. Furthermore, for those who have bucket seats and a factory center console, Hurst also offers an offset shifter to position it perfectly in the stock hole.

Project Olds is just about finished, and by the time you read this, the fuel system, exhaust, and cooling system will already be completed. One of the last items to be bolted up before firing up the 461 was an MSD 6AL2 ignition box, which we mounted underdash for quick and easy rev-limit adjustments.
