In the next post is the promised email letter I received from Brian Clarke (President of BHJ Products) containing their company response to the issue posted earlier on their SC/XR7 dampers.
For those of you that are unfamiliar with previous posts on the subject, here are a few links for reference:

SCCoA FAQ:
(This will be updated with the new BHJ damper installation document and also the wording on the brightly colored tag that will now be attached to each damper. Brian is forwarding that new information to me.)

There were a total of 11 late model dampers (94-95) that were sold by BHJ that had a stock center bore depth. These were serial numbers 31548 – 31558 (10 to Super Coupe Performance and 1 to Blue Tongue).
All early style dampers and all other late model dampers have the raised center bore. This will remain unchanged on all dampers manufactured in the future.
While there have been no reported issues with using the stock or Mustang damper bolt, an M14 x 1.5 in a 50mm bolt length will give about the same thread engagement as the stock bolt. The BHJ dampers are .425" thicker (approximately 11mm) in the center bore area. The stock bolt was approximately 40mm in length. Replacement bolt should be of the same strength as the stock one, 10.8. Also, use the thick washer like was used on the stock damper.
Big thanks to Brian for taking the time to address this issue that has been a concern of many damper purchasers and potential purchasers. Also, thanks to the posters who brought this to everyone's attention and worked on sources for the longer bolts.
Brian does not frequent the boards very often, but I have offered to forward any outstanding questions to him via email.
