I actually have about 10 sets of brand new OEM SR20DET Starter bolts.
I also have a brand new OEM starter and two brand new Mishimoto starters if interested.
If you are just trying to pick some up at your local hardware store (ew) then the measurements are.
Upper bolt: M10 x 1.50 60mm UHL
Bottom bolt: M10 x 1.50 80mm UHL
UHL = (Under head length)
