Driveshaft
You'll need a 3-bolt to 4-bolt adapter for the Genesis differential. I used the Collins adapter. Note: only the Spicer 3-2-119 yoke works — the others they list will not.
I ordered my driveshaft from Ron Wicks at PST (Precision Shaft Technologies): 3.5" aluminum with a Strange front yoke. Your driveshaft length depends on the transmission and engine mounts you use.
Off-the-Shelf Option
Sikky sells one-piece driveshafts sized for their mounts, with high-strength U-joints, for 4-bolt differential flanges:
| Shaft | Price |
|---|---|
| 3" steel, T56 (SKHYSH1-S) | $709.99 |
| 3.5" aluminum, T56 (SKHYSH1-A) | $939.99 |
| Aluminum, TR6060 (SKHYSH2-A) | $1,349.99 |
Only order an off-the-shelf length if you're using that brand's mounts and transmission. Otherwise measure with the car at ride height and have one built.
