Did a little calling around and got some more info on the strut extensions. My local distributor and his contact at BDS couldn't find them (they came packaged with the front coils). So I called a rep at BDS and got a part number. With the part number my local distributor is able to order them.
BDS Strut Extension
Suzuki Sidekick and Geo Tracker
Part# FSE3
$29.95 each (you need a pair)
Now I just have to decide if I want to try another work around for my problem or pay $60 for a pair of these. Makes you wonder if you could just buy some steel rod, drill it, tap it, and thread the top. It would be very tempting if I had access to a drill press.
