What is the issue? They are very short, but I'm not sure how many variants, if any, there are.A lot more variants w/the 225, many different bodies/applications, but the 170 pretty much only A-bodies,
@slantsixdan ......with Dan's parts catalogs the numbers would've called 'em out.
Dana's suggestion is the best if You're not sure if You even have the correct stick for the OE tube.....
