Many thanks to Forum member rick for researching and testing out this replacement…
“I have Dimension IV I bought brand new in 1986. one of the string retainer claws finally broke.
After an extensive search for replacement parts I decided to search for an entire replacement system. The Floyds require the neck to be shimmed in order to obtain proper intonation. I located a FR licensed replacement on Guitar Fetish. It is black and made of high quality material. Not the pot metal so many are made of. It dropped right in.
I even left the original posts in. Perfect scale/intonation. It is also a fast load design so no cutting strings. You can use any strings you want!
I have been using it for a couple months and it performs GREAT.”
