You will have to change to a TKO style bellhousing.
The TKO-500 has a 10 spline input shaft, but if you install a TKO-600, you’ll need to use a 26 spline clutch disc.
You will need a speedometer delete plug, and use an electronic speedo pigtail.
The factory crossmember will work, but it’ll require new holes in the floor board to bolt it in.
You will need a driveshaft spacer (that we can provide), or a new (longer) driveshaft.
