When I purchased a Foxbody Mustang manual steering conversion kit for a turbo LSx swap project…the instructions strictly warned me to (once all the different u-joints and steering shafts were in place)…to drill receiver holes for the set screws through the set screw holes in the various steering joints.

I drove that car in real Canadian winter (snow and -20 C)…and of course in summer… no problemo.

So when I built my turbo BBC ‘35 FFR truck…of course followed the same plan. Put some miles on it over two years, and trust me, with that kind of HP under my right foot…I checked those set screws several times. And they never loosened.

Makes me wonder why the kit instructions don’t mention this tidbit.

I think if you do that, plus of course Red Loctite, you’ll be golden.
