Hey guys just bought myself a WG a few weeks ago to use as a daily/tow car and have been going thru it to make it reliable. I came across the forum and found some very useful tips and thought after doing some work to the Jeep I would add a little info
Nuline Idler tensioner pulley is now part EP101 which is still steel but has only one side wall making it lighter.
I did a reco on my alternator as the clutch was stuffed and got the clutch and pulleys from here. ( clutch $82 )

they didn't have everything in stock but got it ordered in for a total around $200
I also found brushes for the alternator online

And slip ring here if you need it

Also as these alternators a very hard to find at a good price this one looks like it will fit if you swap out the brushes for the link above and maybe rotate the rear cover 90 degrees to line up the two pin plug on brush unit better.
