Throttle Position Switches

However you want to do it. Selling the throttle body assembly or just the
switches. I suppose I could go either way. I would like to save some
cash, but on the other hand it wouldn't be bad to have the o.e. throttle.
The one I have on there is for the coupe gt 87.5 special build or is
supposed to be and the accelerator cable is too long for it without
spacers. And I had to adjust the position of the idle switch plug because
it was in the same place as the cold start valve. Yet, I all ready did a
very good job cleaning it and making the aforementioned adjustments. So
whether I changed the throttle body now or just had it on hand it might be
worth it. Let me know how you want to do it.
