Steering column thread

[ptegler]

anyone have any clue as to the thread and spline (which car) was used for the Chris Custer Rotus cars? (specifically the later year runs)

Looking for a steering wheel boss to fit the column and have no idea where to look.

I don't know for sure but if you have a metric dial caliper you can measure the OD and thread pitch. It could be M12 x 1.25 if it's a Toyota-based steering column.

My 1989 wears a MOMO dated 10-92 (so, not original) on a K-7713 adapter with a quick release hub.  I believe the K-7713 is 'classic Toyota' adapter and it is still available.

was trying to determine the car the column might have come from specifically for the spline info for a wheel adapter.
I don't know if there were a bunch those years from Toyota?... all the same generically?  diff on every model?

If you don't have a METRIC dial caliper, 1 inch = 25.4 millimeters.

Application notes on the K-7713 show applicability to most (everything?) Toyota made from the early 80s to the mid 90s. There is a strong JDM aftermarket for that period, so I'd expect you have many options.

 

My guess is you have a 33 spline, 15mm diameter shaft. I'll bet Toyota only produced one size with 33 splines, so counting the splines on yours might be your easiest option to confirm compatibility.
