T56 questions...
T56 questions... Just curious, before proceeding with hacking....
I am in the final steps before getting to drive - my engine starts/runs, final wiring is nearly done, got a few odds n ends to iron up here and there, finally I'm down to ... getting the clutch hydraulics done on a truck nobody makes nifty brackets for.
I currently have a brand spanking new F-Body hydraulic cylinder. I have been mulling over various brackets, fabbing them up in light gauge steel and testing fitment using the stock cylinder. Well, fitment is a little nasty on my firewall because of the angled mount on the cylinder, and I'd prefer to find a different cylinder setup that will plug direclty into the T56.
I wonder:
1) Can anyone recommend alternative *affordable* hydraulic cylinders out that will plug directly (no-mods) into the T56? I would prefer it was not F-body, that damned angle is giving me grief enough.
2) If not, what is the best way to locate a chunk of F-body firewall? I checked my local boneyards, all in vain. I honestly am OK with just welding a slab of F-Body firewall into my truck!
TIA

So you would rather cut and weld the firewall than modify the clutch hydraulic line?
Why not use a Tilton or CNC or Willwood 3/4" master cylinder? They all have a flat perpendicular mounting face.

Why not try using and modifing the adapter that is used to adapt the F-body Master to the firewall of 1st Gen Camaros, Nova and Chevelles, look in the FAQ for the Camaro swap.. I used it on my Chevelle. I built mine out of 1/8" steel.. (I think 3/16" would be better tho...) ATS and S&P market them. You can check out what they did at S%P web site on the installs.
With a little fab'in, you should be able to modify something to work.. don't give up.. this is what working on cars and modifing them is all about.. getting something to work !

I would prefer to find something that mounts perpendicular and has a fitting that mates to the T56 - will check out your links. It would be cool if I didn't need to bleed it, too, kinda like the stock unit comes (w/resevoir and line - just mount and hook up)

Been there, done that, modified the S&P unit to bolt up, but just could not get a nice, neat tucked away angle without doing some serious cutting of the support structure of the firewall. Meanwhile, anywhere to the left of the support structure shown in this pic:
will cause the cylinder to sit 2" deep into my inner fender (because of the angle of the cylinder).
I already have the 3/16" mild steel plate to fab a bracket. I would truly like to find an alternate solution, though, because this one will "work" and "operate" properly, but it absolutely will not come off looking "clean" enough for my taste.
My friend drives a late model S10 (2001?) and the clutch pedal is squishy as hell. I will check his out also - might be a closer swap, although I won't like the feel of the clutch if it's anything like his.
So, I'm bouncing back and forth between Jegs and Summit, only because they have a lot of pictures to look at (I typically buy from board supporters).
I am a bit confused - you can use a brake MC for the clutch? How do you know what bore and stroke MC to get for this transmission? I think the stock stroke if 15/16", not sure about the bore...any add'l advice appreciated.

The S10 cylinder has a 90 degree mounting surface and has the correct quick disconnect fittings already installed. As for the spongy pedal, that may be isolated to that particular cylinder or the clutch assembly itself. I have one on my T56 without any issues.

Thanks again!!
Damn, ok, I give up. I just wasted 3 hours searching for that part number on the web and netted nothing. Next three hours would be better spent wasted trying to fab a bracket. If the part number ever comes to mind, that would be great. Otherwise, might consider going with aftermarket 3/4" bore, 1" stroke MC from Wilwood and just ... get a fitting made or something to adapt the line..
Try using some of the major parts stores web site for searching.. I find a lot of part with picture that can give you some general ideas of what will or will not work.. I have used Carparts and cskauto

I have the hole location to punch through the firewall, and the GreenLee punch to do it with, and I have the complete F-Body master cylinder setup w/resevoir and hoses...I think this is just another case of, "I need to stop being so damned perfect" and just move on.
Don't take me the wrong way. I know it's easy to read feelings into posts, I'm not freaking out or anything, just coming to the sad realization that it's less frustrating and more enjoyable to fab something up than it is to spend some $$ and wait even longer, and still do some fab work.
My last stop was actually what bczee suggested - I hit 'ol faithful's website (NAPA) and looked up the '98 and '99 1500 pickup master, and also the 02 S10 master. Both are very similar looking and would work, I suppose. I just don't want to spend $80 on one, then transfer the resevoir from my F-body setup, then the hoses, then ... meh. Trading work for work, y'know?

they have picture too...check out the one for a '85 ranger with the base 4cyl.

You can look up a lot of the parts at gmpartsdirect.com or go directly to AC Delco. GMParts direct has a catalog function which will help you find the PN. If you enter the PN on AC Delco`s website you can get images of many of the parts. I don`t remember the delco website, I just google AC Delco whenever I need it.

i "think" the correct part is named "cylinder", but there are three listed for the S10 in particular: "inline", "V6" and "universal".The "universal" part number tracks back to the same part used in the 98-02 F-body. At one point for the S10's, I saw a part number for the F-body MC that preceds the current one (the MC w/all of the problems in the early 2000's)
I appreciate the suggestions.
