I just bought my first car, a 99' Wrangler Sahara edition a couple of weeks ago and started restoration. Previous owner had winch, LED bar, Fog lights, amp, pre amp, etc. I'm guessing my alternator is the 117 amp, if that's the case, is it enough for running all of the above or should I upgrade it? I did a little research and I read some people mentioning the 160 amp Durango alternator is a better option but I'm not sure if it actually fits my 99' and if its really worth it, again this is my first car and I'm new to this. Thanks in advance!

You are fine,I run fridge,etc no problems at all.
 
Ain't broke don't fix it

However if you do find yourself needing a new one...go for it....

I'd concentrate on all the 25 year old rubber bits that are probably shot. Engine and transmission mounts. Crank pulley has rubber. PCV valve grommets. Vent lines for the axle and transfer case.
