Cant help you much more than just info, but:
I recently picked up an '89 TBI engine with
serpentine brackets...with two main brackets.
Pass-side holds the R-4 A/C compressor,
idler-arm and has provisions for an air-pump,
which is not there. The drivers side holds
the alternator and p/s pump.
But in scouting the yards, I ran across the
pass-side bracket with-out the extra flange
to mount the air pump, which I am going to go back this weekend and see if I cant get
it. I did get the casting number off of it
and inquired at the dealer as to the cost,
i think it was around 90.00 for just that
piece. I dont have the p/n handy but if you
email me, i can get them to you.
The peice without the air pump flange is a
much cleaner and nicer looking piece.
Just keep looking, you'll run across something with the right price.
I converted my (do i dare say it) mustang over from v-belt to serpentine when my
alternator failed and got all the parts from
a salvage-yard mustang for 100bucks, that
was a good deal. There is a picture of that
engine on my website.
GoodLuck,
