UrS4 Strut pinch bolt size & Bira brake bracket interference

[dgraber460 at aol.com]

My understanding (which is only hearsay, and my own assumptions) is that a grade 8 would be more than sufficient, and easily sourced.
My other assumption is that it is head forward so that in the rare case the nut vibrates off, the bolt will be more likely to stay in place.
Anyone with the true engineering "facts", feel free to chime in.

Hello All
Is the strut/ball joint pinch bolt a off the shelf or a dealer only part.
ither way does someone have a spec or a part number.
I had to grind the head off to remove thebolt and strut, because the Bira
racket for the BBK prevent easy extraction,  the Bentley indicates that the
ead should point forward, with the brake bracket it the way that will be
mpossible without removal of the bracket which I am relunctant to do. Why
oes the bolt need to be instalelled in this direction and will it be a bad
dea to install backwards to aid future removal.
TIA,
Chris
