Hey there snj8198. I think it's a sm465 because it has a 3 speeds (L, 1-3, R). I think I can get an OD for it, but haven't really looked into it much. It's a really nice "nice-to-have" though, so it's low on my list of priority upgrades/fixes.

I think 255/86 might be the way to go for me. I've always liked the 235/85 tires but think they are too small for my gearing. The 255/85 tires should fit my 16x6.5 steelies, right?

Otherwise I'm eye-balling military 37's but I'm pretty sure I would need a lift to get those on.
