If anyone in FOT land could provide the dimension for the shoulder, I would appreciate it. I have the under head length but there's no measurement for the shoulder on the ARP web site. Else, if you or someone you love ever had a reason to "repair" a posi-unit after a ring gear attachment "problem", I'd be interested to know either a replacement fastener part number or advice on repairing the posi unit, I'm all ears. Translation: I may have to ream out the mounting bolts holes in the TranX to get everything kosher and I'm looking for anyone that has related experience with same.</div><div class="ydp621827b8yahoo-style-wrap" style="font-family: Helvetica Neue, Helvetica, Arial, sans-serif; font-size: 13px;"><br></div><div class="ydp621827b8yahoo-style-wrap" style="font-family: Helvetica Neue, Helvetica, Arial, sans-serif; font-size: 13px;">Regards,</div><div class="ydp621827b8yahoo-style-wrap" style="font-family: Helvetica Neue, Helvetica, Arial, sans-serif; font-size: 13px;">Bob Lang<br></div></body></html>
