If it is a 4 speed it's an SJ-410.

They aren't bad rigs, I've certainly enjoyed mine. At this point though, I'm running Sammy axles and transfer case. Your a bit underpowered at 45hp compared to the 65 of an SJ-413.
Your transfer case is 10% lower then a stock Sammy transfer case. Top speed stock is 60 mph. Axles are 3" shorter in length, and your springs are 3" closer together then on a Samurai so any axle swaps will need the spring pads moved 1.5" in. Metal slotted front grill, much cooler then stock Sammy grill. Comes with 4.10 gears in the diffs instead of the 3.89s. Different sized diff, but you can order Lockrights for them. Smaller axles, same size knuckles and hubs though.
You can fix the shifter yourself, you just need to pull it off and replace the bolt that is broken. I know Hawk Suzuki makes the new shifter for the Samurai. If you want, you could probably just call them and have a used SJ-410 shifter sent to you.
Or if you wait until this weekend, I can check in the shop and see if my spare transmission has one on it.
