Re: Project 1966 K20 adventure rig

Still progressing with this beast and finishing up the detail work.

I finally got around to installing shocks at the rear axle. They are Bilstein 5100 series units. The bushings on these shocks use 1/2 Inch bolts. To fit 1/2 inch bolts into the upper factory 3/4 inch mounting holes, I used some 3/4 inch outside diameter dom tubing with .120 wall(.510 inch inside diameter) to sleeve those upper mounting holes. The lower mounts are stout aftermarket sourced with 1/2 inch bolt holes.

To address the driveline vibration at 50+ mph, I've decided on CV joint at the transfer case end. And at the rear axle end I used a 4 degree shim to get the pinion and driveshaft on the same angle. I also had to change out the t-case rear output yoke to a CV style. Should get the driveshaft back from the shop next week.

The interior configuration is now the way it is going to stay so it was time to trim down and bend the main transmission shifter. I put some heat to it and made a bend towards the driver. Then I removed about 8 inches between the bend and the shift knob. Then I welded back together. Way more comfortable shifting position now.
