oohh bu55er Bill, i see you are suffering 'tailpeice bolt hole syndrome' ... all my srx (twinshocks) have succumbed to that ... i heat up a washer and melt it into the plastic, then cover with a thin layer of fibreglass mat, drill it out when set, and seems to do the trick.
just saying.
I've been following this thread with interest, but as i only have #1 in the stable now i'm unable to help, as many years ago i wired in a boyer/brandsen reg , a really good fix, done many 1000's of miles faultlessly.
pip pip
