Randall Rack Power Steering System - A-Rack-Naphobia

The passenger side mounts horizontally to the old idler arm mounting points and vertically through the old crossmember point. No need to mess with the front suspension or its mounting point.

Header clearance has long been a problem with rack upgrades because the steering shaft wants to cut right across where the old-style header use to run. JBA has taken care of this problem with its new mid-length header that runs back before it turns down. It makes most clearance problems all but fade away.

Here is a side-by-side comparison between the new JBA header and an old-school header (actually for a 351W). The older design starts moving downhill almost immediately, taking advantage of real estate not being used. The new design works its way back before slanting down towards the transmission tunnel.

Here you can see why so many people run into clearance problems with the old-style headers. The front two pipes are running right across where the steering shaft wants to go. It wasn't a problem with the old-style steering gear that bolted to the framerail.

This shows how the up-and-over design of the JBA header helps clear the steering-shaft assembly. We had absolutely no problems at all with our header install.

Since our Mustang is a '70 model, we have the ignition key in the column that locks the transmission and steering wheel when the key is removed. To modify the column, it's easier to pull it out and make the changes on a bench.

The extra little lever on the end of the shaft is our biggest concern. This round tube attaches to the transmission and prevents the tranny from shifting without the key in the lock. When we are done, the steering wheel will still lock, but this lever will be gone.

The lower end of the steering shaft slips into the upper shaft to provide safety in a wreck. The column slides together preventing (hopefully) the shaft from piercing the driver. The new shaft retains this collapsible-column safety feature.

Here's the new column shaft assembly with the new bearing and collapsible shaft in place.
