Wiper blades are 11 inches long. You can get them at any 4WD place that sells Jeep stuff.
I would also change all the fluids in the axles, the tranny and transfer case. That could
possibly make it shift better, as you don't know what the hell is in there now.
Also, change the antifreeze. You don't know how long the Jeep has sat around, so
that could be bad also.
For oil, you can run 10W-30 or 10W-40. Thats what is recommened in the service manual for
temperatures that go down to 0 degrees F. Below that, and it recommends either 5W-20
Also, go to your local Pepboys or any other online car place, and pick up a Haynes
manual for it. It costs about 20 bucks or so, and will help you with all the routine
maintainence you need to perform on the Jeep, as well as tell you all the requirements
for the fluid viscosities and what not.
And, as mentioned before, where are the pictures of this miracle Christmas in March Jeep?????
