The Ford Motorsport 24# injectors are a direct drop in for the 85-86 32V motor. The o-rings do not need to be swapped.
Part Number is 9593-A302.
This is how I would go, rather than have injectors cleaned. You can buy them online from ebay or many other places and they are better than stock.

I was having a brain fart on the size of injectors.

Or, if you're looking for a fun hobby, you can do it yourself with a spare fuel pump, a jump start box, a push button switch, a pan of b12 chemtool and a Mustang injector rebuild kit from ebay, but after doing it that way, I'd say it's not worth the hassle.
. . . Plus, if you do it sitting on the floor and overpressure the pump, spraying b12 chemtool down into your shoes and socks, it burns like crazy for a good 10 minutes. Don't ask how I know.

My recommendation is always: Don't do it.
You can get a set of Ford Racing injectors for about the same price. 4 hole, brand new and they drop right in.
I'm not a fan of refurbing injectors. I think they're a wear item that are cheap enough to replace that it doesn't make sense to hang on to the old ones.
Edit: Guess I took too long to post.
Check BlueOvalRacing. It's where I got mine. I don't think Roger has these because he can't get them any cheaper than they sell them for.
I thought the S3s were 24 lb injectors though. I don't remember.

The chart below reflects my experience with "injector cleaning." It resolved the problem (missing, stumbling, poor performance) completely.

For '85/'86 the injectors are 24lb/hour, high impedence.
It seems as though Ford has discontinued their 19lb/hr injectors, and their 24lb/hour injectors now have what's called a USCAR connector. They sell a USCAR to Bosch adapter. This info is from the Ford Racing Catalog.
I checked Summit and Jegs. The smallest Ford Racing injector from Summit is 30lb/hour.
Jegs carries the 24lb/hour injector with the USCAR connector for $189. For this you have to buy the adapters which are $40 for a set of 8. While it sucks to have to use adapters, the price is pretty good.
Fiveohmotorsport has the 19lb/hour injectors available for $289. They have gray tops. Never seen ones that look like this. The 24lb/hour injectors are also available for $320 for Ford/Bosch. They also carry Denso 24lb/hour injectors for $235. If I needed injectors, I'd take a crack at the Densos because that's the kind of **** I like to try to get away with.
