Do you have the bracket ?

You'll need to either have someone remove the bracket for the master or send you a donor section of the firewall and then carefully drill out the spot welds. God I've done a lot of crazy things to my car!

Biggest question is do I have to pull the motor to install the clutch cylinder bracket. Can I do it from under the car and with the drivers seat removed other than that is it pretty much a swap out.

I did this with the engine removed at the time for other reasons. Removing the seat and the lower bolster/tray on the drivers side will make it much easier....
Great link Sterling, that is a very informative link for those wanting or contemplating this swap

I had found that and have read it many times and it does not look too bad which is easy to say now. Any way to get to the rest of this link?

I did this once, used a unibit to drill all the spot welds, did the swap with the engine in the car. The clutch master feed line runs from the master cylinder reservoir to the clutch slave cylinder I was able to feed this thru the new hole I made next to the brake pedal. (feeding the new line in and up next to the firewall)
The most important part is to find the exact spot to make the hole!!! The clutch pedal cylinder bracket is almost the shape of exactly where it needs to be so it's not exactly a guessing game. Once I confirmed a few measured points I made the hole, I put the clutch pedal assembly together and used sheet metal screws until I could confirm that everything worked , two days later I spot welded it with a MiG.
I had to correct the idle and AC unit step up, along with a jumper in the fuse box (neutral safety)

Yes. I just did this on my '88 5 sp. A pain in the ***, but totally doable, no rocket science to it.

See post # 5 here for a couple of pics. Not a tutorial, but the pics might help you see how to access the mounting bolts on the clutch master.

Cliff,

Have you confirmed that the bracket is not there on the firewall of your S4?

Mine was there on my '85 auto. Here's a pic of the hole taken from under the dash. The hole you see is not the bracket, you have to bend back the thick plastic material to actually see if the bracket is there.



Only takes a minute to check, and if you already have it, you are golden.

If your doing pre "82" no need for firewall mod. Just drill holes. Not sure about newer years. I've done two "79" & "82" both had boss in firewall just needed holes for mas. cyl. mount. Like others said not to bad. The prob's come when you use old parts for new job! Put in all new ,you dont want to go back in there if you can help it. 928intl. or P.Parts has new M. cyl. & slave, get new hoses! Remember used parts are just that...used parts.
Good luck,
JohnA

Hey Ed,
What year?
Thought the boss in firewall ended in my "84" ?
Cool if not. I'm looking at "88" auto.

I wouldnt even bother to attempt cutting that hole without pulling the engine out. It is quick and easy to get the engine out. While it is out you can do alot of things with ease.

Or consider using a floor mounted pedal assembly. But it doesnt look stock.

Hi John,

My '85 auto had the clutch master bracket on the firewall, if that is what you mean. I've heard that this is the exception rather then the rule though, for an auto to have the bracket, but can't speak authoritatively on that. But like I said before, its worth taking a look on an auto as it only takes a minute.

I, too, did mine with the engine in the car. Not really that hard to do- it helps to have the car far enough off the ground that you can reach up under the dash easily. I didn't remove the seat, just moved it back. Sadly, I don't have any pics...
