89 model is abit on the fenceline if you know what i mean. Widetrack or narrowtrack?
88' model are definate 1L NT where as
91' model are definate 1.3 WT
89' are changeover miscellaneous parts
1.3 Wt Have 3.7 diffs with 2 pin front diffs.
1.3 Nt Have 3.9's with 4pin front diffs(better for lockers)
I think it should have a standard 1.3 transfer. Unsure of ratios. Or if it has 4wd light.
Is it a Swb or Lwb?
Is it a genuine Suzuki? Not one of those mix'n'match super miscellaneous SWB/LWB maruti's?
Also with the oil, what did you use in the Lj? It should be 80w and 90w diffs and gearbox. I have forgotten which oil 80/90w goes in where
I use 20w for my motor
Hope that helps
