Guibo Bolt Shoulder Length

[amdavidson]

Does anyone know (or can measure) the shoulder length on an 8 bolt guibo bolt?

I'm trying to find new hardware locally and know they're M10x61 according to RealOEM, but don't know how long the shoulder is.

Thanks.

At a minimum, the shoulder should be the same length as the metal sleeve within the guibo. Also remember that the head of the bolt must rest against the guibo, and not the flange of the transmission output or the flange of the driveshaft (in other words, the nut is tightened against the flange, and not the guibo's metal sleeve).

8 bolt guibo measures 1.500 inches. 6 bolt measures 1.105 inches.
