By any chance does anyone have the thread size measured out for the Ralco RZ short shifter? (00+) I have already searched the forum for anything and there wasn't any information, same with the internet. Plus I do not have the means to measure the size of the threads. Using the knob that came with the shifter isn't any fun in the sun.
take either the knob it came with or the shifter (if its not installed) and go in ACE or Home Deopt or somthing of the sort and on the thread checker wall try threading it until you get the right one.
