A note of clarification on the previous post. The '85 - '87 v-belt system is not considered "serpentine" because it consists of multiple belts. The '88 - '92 system is a true serpentine. I just converted my '87 to a serpentine system where I used parts from a '92 305 RS.

This would depend what what parts you can obtain from a junk yard. Since I already had every part including nuts, bolts and bracketry, I can't help here.
I can tell you that you will need the following:
1) Both accessory brackets,
2) Three support brackets (one on driver's side and two for the passenger side),
3) Alternator (different mounting hole location,
4) A/C compressor (different design),
5) A/C compressor electrical connector,
6) A/C line assembly,
7)Water pump (reverse flow on serpentine) with pulley,
8) Power steering pump with pulley,
9) Assorted Torx bolts, & a
10) Serpentine belt.
I did not confirm whether the air pump is different. To do this, call an auto parts store and see if the part numbers for an '85 - '87 is different from an '88 - '92.
In addition, wiring length needs to be modified for the A/C and alternator, now that they are on opposite sides.
There are two ways to route the new wiring. You can mish-mash them across the front of the engine or do it correctly by breaking them out of the original wiring looms to the rear of the engine and relocating them to the "new" right and left sides.
| 2 - what new parts are needed? |
Again, this depends on whether you're comfortable reusing an old water pump, etc. I bought a new Stewart water pump and alternator.
| 3 - any place that I could get detailed/step by step instructions on the conversion process? |
I don't think anyone has taken the time to write up instructions, but if you need help, I can supply whatever info you need.
