1992 Chrysler Town & Country 3.3L

My serp belt slipped off yesterday morning when I started my vehicle. Last night my tensioner pulley was off plane and when torking it it snaped off and the pulley, part of the assembly, and the spring all came flying off. Today I'm going to tackle replacing it, and I've done my searching on these forums.

So from what I'm gathering, there is one mounting nut/bolt holding the assembly on, and to get to it I need to be under the van with a long extension to reach it? I'm only asking because most of what my searching turned up was for 1996 and later model T&C's, and I know my van is a gen II T&C (1991 thru 1995) so perhaps something could be different?

Thanks so much!
