As far as I can determine, only cars with AM radios were equipped with the quart clock (FM radios had digital clocks built in).

Its a Nevada car. Sat outside for quite some time so the paint is really faded. Needs stuff here and there. Will be a good project after I finish my 86 Trans Am.

Re: How many '85 SILVER IROC-Z's were produced?

Just to clear up some facts on G80 availabilty in late model production.
I ordered my 85 IROC in late march, built in CA. In late April the dealer called and said that the factory called and wanted to know if I still wanted the car as it would not be produced with the G80 option I ordered as there would be no more produced that year due to shortage of the G80 limited slip. However they said they could still give me the GU6 3.42 gears and the J65 rear discs. I told them to continue with the build. I ordered mine with less creature comforts and all performance options.
Black and gold. No special interior was requested so it came with base saddle color vinyl seating. Power window,. elec. rear hatch release, AM/FM no rear speakers, A/C, LB9, 700r4 trans, rear disk and 3.42 gear, no T-Tops. Car was lighter than heavily equipped cars and would run fender to fender with the later 350 iroc cars. Never had a stock mustang out run me, not even close. Currently has 43K on the clock but needs some freshening up from sitting. After all these years finally its worth something...

This is the first confirmation that the factory ran out of the G80 option during April of 1985. This is why the RPO 1C5 "California" IROCs all came with GU6 3.42 performance gears, J65 4 way disks which supposedly weren't available without ordering and having the G80 "posi" option. All 502 of these cars were built in the third week of April 1985 when the G80 option had run out. They did however get the GU6 3.42 Performance gears and J65 4 way disk brakes, but no G80. Thanks for that information. Now I'm wondering if the Norwood built cars ran into the same problem as the west coast cars.

Interesting, thanks!

My '85 is a May, Van Nuys build with a GU6 and no posi. A ridiculous combo with an L69 cammed LB9. The right rear goes up in smoke at half throttle.

Re: How many '85 SILVER IROC-Z's were produced?

I have a 1985 IROC Silver Metallic I bought brand new in Nov. 1984. The only mods I have made
are an engine swap from Lg4 to a crate Chevy 350 hp 350 Cu in. and gear swap from
3:23 to 3:73. and dual exhaust. It is 5 spd, T-tops. black and grey interior. I have kept all original parts.
original mileage 72,000 all mods were done only 3,000 miles ago. I felt originally it was grossly underpowered.
stored every year from Nov 1 to April 15. Like new.
