I don't know what the factory specs said but at present there are two sizes of REPRO (needles / GAV housings) manufactured that I have seen.

1. One is about 0.170 shaft diameter.

2. The other is about 0.160.

I find several different sizes of used needles also ...

So when you find a (needle / GAV housing assembly) it is best to check the fit.

Easiest way is to (insert ie slide) the needle "Backwards" that is instead of screwing needle into threaded end of GAV ... insert needle into the end of GAV closest to the "ring" and check the fit to see if it is very loose or too tight to turn...

You must buy both REPRO needle and GAV housing from same supplier.
