BAC No Cut Coupler Mopar 73 B Body

Several customers asked, and we delivered: this no-cut 73 B Body coupler makes an updated steering box a true bolt-in on 1973 and some 1974 Mopar B-bodies with isolated steering columns.

What the 73 B Body coupler replaces

On these cars, a small cast-iron adapter sits between the rubber steering column isolator and the steering box. However, that factory part doesn’t suit the modern quick-ratio boxes. Our direct-fit coupler simply replaces it, so you don’t have to cut or modify the steering shaft.

The product photo shows the original part next to the new coupler, so you can see exactly what comes out. Because the coupler uses your factory hardware, installation stays clean and simple. As a result, fitting a Borgeson updated steering box becomes a snap.

Fitment and installation

This 73 B Body coupler fits 1973 B-bodies and some 1974 B-bodies that use the rubber-isolated steering column. If you’re not sure which column your car has, look for the rubber isolator disc at the bottom of the shaft. Better yet, give us a call before you order.

• Direct fit, no cutting
• Uses the original hardware
• Made for updated quick-ratio steering boxes

Also, plan the rest of the conversion at the same time. An updated box needs pressure and return fittings, and we recommend a power steering cooler, since modern boxes run at higher pressure. For a complete package, see our steering box kit for the 73 B-body.

Why does a no-cut design matter? A cut-and-pin fix works, but it changes your original steering shaft for good. With this coupler, on the other hand, the factory shaft stays intact. So if you ever want to go back to stock, you can. In addition, the factory rubber isolator stays in place, which keeps road vibration out of the steering wheel.
