Pin drive bolts splitting Help Please

[cdnus]

After reading butz999 post about runout on his adapters I thought I would spend a little time checking mine out.
1st.
I removed 1 nut & checked the angle- 60deg taper(or 120deg total)
still confused on the correct termonology.
The taper was FULLY seated as indicated by the dulling of the entire surface.
The countersunk hole was similarily dulled indicating a correct matching of the nut & adapter angle. (120deg.)

2nd.
Mounted a dial indicator & measured runout @ the outward end of the snout--Hub 1-.003, hub2-.007
Measured the hubs that the adapters are mounted to & they had .003 runout on the mounting face.

3rd.
Measured the pin location by positioning the indicator to measure the outside location of each pin while rotating the hub through 360deg. (hope I have splained that correctly)
Hub 1--4 pins .000-.001, 1 pin +.005
Hub 2--3 pins .000-.001, 1 pin +.005, 1 pin + .007

4th.
Measured with dial verniers the pin location from OD to OD of 2 pins working my way around untill all 5 were measured-- Max variance was approx. .003.

Conclusion:

Vintage makes & supplies a excellent product & is very good dollar value.

My only complaint was the original nuts supplied in 2005 were too soft & the hex stripped very easily. Bob replaced them with a improved version N/C immediately & after making up the tool to install & remove them(mentioned earlier in this thread) I have had NO problems & my car runs very smooth at any speed.

P.S.
I checked the front only--too lazy to do all 4.
