Would this be for a 2dr or 4dr?
I'd check out 4x4pirate under Suzuki. There is a thread there about a SAS on a Trackick and some pics of one or 2. Toyota axles seem to be the choice, however, there is one with Scout axles.
Why not Jeep narrow axles, D30 front, AMC20 or D44 rear? (And don't rip on using the Jeep axles as it may work, probably plentiful in the yards, and parts are readily available.)
