You guys with LS motors and IROC steering box................

[BuddyP]

Where the heck did you get a rag joint/universal from your steering column to steering box input shaft? I have a ididit column which is a 1"x48 and hell if I know what size the IROC steering box input shaft is. Also what is 18mm DD, I found a rag joint labed 1x48 and 18mm DD, what is "DD"? Would that be the IROC input shaft size by chance?

I thought these things were a dime a dozen and I'm having a heck of a time finding these!

EDIT.... ok not sure why I noted LS motor since it's irrelevant to this question. Doh! Meant to say IROC box and ididit columns.

DD refers to a double d shaft. Simply a round shaft that has a flat milled on both sides of it. Google double D shaft and you will find many suppliers for DD.

Ok, well I just called ididit and they are telling me the IROC box input shaft is a 3/4" 30 spline. I went ahead and ordered it while on the phone with them... will know if that's correct or not in a couple days.
