Good writeup. My son is driving it back (in 4th gear only, builds character!) from western MA tomorrow, so I'll be able to look at it then. I presume I have a V5MT1-1 (truck is a '91) but from what I can see, the -3 is a better unit..

2 dr Monteros;
1988 2.6 LSD 5 sp - RIP, hit in rear
1989 3.0 5sp now belongs to Jim_B!

4 dr (1); 1991, LS. m/t sold
4 dr (2); 1991, LS, A/T. New engine. Oops. Needs another engine.
