89oldscutlass Posted May 10, 2004 Report Share Posted May 10, 2004 Guys im in the middle of doing my swap on my Cutty. I guess Im lucky to have had a 5 speed Cutty to get my parts from. My question is what did you do about your slave cylinder hole on your firewall my cutlass has a round one there but it needs to be square for the slave to turn and lock in? Ive did swaps like this on many old muscle cars I have had and they were simple compared to this. I have a new respect for you guys who have done this swap and any tricks would be apreciated. Oh and one more thing getting those pedals out were hell and dread having to reinstall them on my Cutlass. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted May 10, 2004 Report Share Posted May 10, 2004 the hole in the firewall is actually for the clutch master cylinder; the slave cylinder is the one on your transmission on the other end of the hydraulic line. anywayz, i bought a Dremel tool with an 18" flexshaft and a tungsten carbide cutter just for the job. that made it extremely easy, and i didn't have to remove the brake booster or anything. took about 5 minutes and the master cylinder turned & locked right in. just be sure to cut very little and test fit often, because if you cut too much you'd be kinda screwed - that tungsten carbide cutter cut thru the firewall sheetmetal like a hot knife thru butter. good luck. btw, i thought the pedals were the hardest part of the job, ecspecially the brake pedal installation. i would take the front seat out and drop or remove the steering column for better access.

Baddflash Posted May 11, 2004 Report Share Posted May 11, 2004 take a look at my site I'm just about finished the swap. There's a few pics showing that master cylinder hole. http://www.cardomain.com/memberpage/386684/6 One thing, the position of that whole has to be exact if you screw up you'll have to replace that panel. I managed to luck out and got it perfect, although I doubt I'd get it right the next. As far as the pedals, I removed everything so I could pull the pedal pan out a few inch's which made them easy to do but a huge amount of work to get there. I was removing everything anyway so it worked out good. Now I just need time to finish. Quote Link to comment Share on other sites More sharing options...

I was removing everything anyway so it worked out good. Now I just need time to finish. that's interesting about the pedals. mine came from a '90 GP also and i didn't have to drill the brake rod out. i never removed my dash to install the pedals, but i think maybe it is easier that way. i can't believe i ever got them installed; i remember laying upside down in my car with my head crammed up under the dash, so i could halfway see what i was doing. i had the steering column laying on top of me and it was like frikkin 90' outside. god that really sucked! i found that a small flourescent tube light really helped out, along with ALOT of patience. i would recommend simply cutting the existing brake pedal shorter and save yourself the hassle of swapping the smaller brake pedal in. installing the clutch pedal really isn't too bad in comparison to the brake pedal. heck the whole 5-speed swap is pretty easy besides trying to install the new brake pedal!

89oldscutlass Posted May 11, 2004 Author Report Share Posted May 11, 2004 Does your cars get a lot better mpg since the swap? I know on the older cars it made a big difference mpg wise as well as making the car quicker with the lighter tranny. Quote Link to comment Share on other sites More sharing options...

Actually the pedals and shifter came from an '89 GP, I found the '90 latter and wasn't going to pull those pedals again. I can't believe you got them changed from under the dash, you definately have more patience then me. I was planning on changing the dash anyway so it was much easier doing it from above. As I already had the pedals in before I realized the problem I just drilled the hole bigger. I agree the pedals are the most difficult part. I have the engine and tranny back in but I have 2 problems, besides the fact I had to get the car out of the shop yesterday. Quote Link to comment Share on other sites More sharing options...
loominaz34 Posted June 7, 2004 Report Share Posted June 7, 2004 If the big idea is just to make the brake pedal smaller, why wouldnt you simply cut it down and fid a replacement rubber pad to fit over the pre-existing pedal? Or is there something I'm missing here? Quote Link to comment Share on other sites More sharing options...
