Hello, anyone with a stock GVR4 or 1g 6 bolt piston handy, I need to know the measurement of the space between pin bores (where the rod attaches)in the bottom of the piston.
Thanks.
Thanks.

I sold all of my precision measuring tools so I apologize for this in advance. Depending on what you or doing it may or may not help. I just pulled my pistons last night. It is 1 3/16" between the two inner surfaces.

How accurate do you need it? I provided a pic in the pistons/rods thread currently being commented on. Maybe that will help as well.
I can measure it, i just forgot to last night.

Matt's measurement provided me ball park, at 30.2 mm. I think it is likely spec'd at 30 +/-.
I saw the drawing you provided (have seen that before as well). Interesting that those dimensions are not 100% accurate to the factory. That states the stock 1g rod small end is 1.140" (28.96 mm), but factory spec is 28.5 mm which is 1.122". I have not looked at all the others in detail yet.
