Seems like forever since my last post. It's been a busy end of summer. Sent my baby girl off to college, bought a new car, moving, works crazy busy, a few birthday parties, kids sports,.. Stuff you guys know all too well.
I plan to spend more time in the shop in November. I did however finish up the 4-link pockets. The rear ends in the car finally. I'm happy with how it turned out. The axle tubes are within .010 on the dial indicator now. Phew.. That was stressful. I never realized the factory 9" rear ends had such large tolerances. Mine was almost .050 out on one side before we started on it. I should be hauling the car down to my dads in the next few weeks to throw on the lift and finish up the bottom side and mock up the engine and trans. |

Here's some pics of the 4-link pockets. I second guessed myself at least half a dozen times on the design and location. Luckily I had Brendon to keep me straight.

I tweaked the rear end geometry and brackets so many times I lost count. After debating over and over and factoring in excellent advise from successful racers like Ron a Sutton and my dad I ended up settling for two different anti-squat configurations. One for road race and a second setup for drag. I'm not 100% sold on arch slotted brackets so I went with multiple holes. The pan hard bar will be slotted as the load is perpendicular to the slot.
Here's some of the brackets off the CNC mill. http://i1158.photobucket.com/albums/...ps5476f1c9.jpg Here's the round stock and bushings my dad turned in the lathe to be able to setup the rear end. We bolted the 3rd member into the housings with shims the same thickness as the thinner gasket to locate the bar which we used for reference with the dial indicator to check the housing ends before I welded them on. We reused the old ends and turned them down to make a step in the tube side to locate them on center. I took most of the pictures with my dad's phone. This is all I have at the moment. http://i1158.photobucket.com/albums/.../null-1437.jpg http://i1158.photobucket.com/albums/...ps9cb190c5.jpg Here's the spacers that go between the brackets and the heim ends. I used 5/8" heim joints with a 3/4" shank and turned and cut left and right hand threads in 1" .156 wall 1022 DOM tubing I picked up from Morrisons shop. http://i1158.photobucket.com/albums/...psc2793361.jpg I set the wheel base to 108". 2 deg pinion angle with the holes in the outside brackets at 90 deg (vertical/plum) and the bottoms of the inner brackets at 0 deg (level) http://i1158.photobucket.com/albums/...ps0aded64b.jpg Here's the finished width. I was barely able to squeeze the 11.5" wheels with 315's in there. The rear end articulates well with a rolled edge on the inside lip of the fender. http://i1158.photobucket.com/albums/...ps9d9f9eb4.jpg |

I installed the trunk lock and threw the front fenders back on to get an idea of the stance. ;). It's been a long time since I've been able to push this thing around on its own 4 wheels. It was nice to get it outside.

Thanks Jeff. The guys at Fikse did a great job for us! This new design will be available soon. I'm really happy with it. They've got a lot of good things going. New designs, more hoop choices and bigger wheel sizes.
