    Pics are pretty large, those of you not on a quick connection, just wait a bit, they will load. Don't ask why they aren't on my main page yet : )

    Did that hydraulic slave cylinder come stock on that? If not, where did you get the parts to convert from manual and how did you do it? Thanks in advance

    The hydraulic stuff came off of (I think '85 was first year) a truck that was originally equipped with hydraulic clutch. Since my tub is an '86, it was designed for the hydraulic stuff, I just drilled through the dimples the factory conveniently makes for the reservoir studs, and bolted it in. Hard to find the parts, not many of the '85 up trucks had manual trannies... :(

    Posted this a few days ago, here you go! : )

    I am still working on finding out what year camaro the tach is that I have in my truck. My dad can't remember what year he got it from, and I have been scouring the wrecking yards for similar...nothing so far..late 80's were totally different...I still think the font/colors look like late 70's early 80's..thats what vintage I would focus on, but would not rule out the 70-81 series, nor mid 80's...

    Just looked on ebay for "camaro tach" and found this http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=578448868&r=0&t=0 the tach is similar to mine, but not exactly...the coloring on mine is closer to the 81-87 trucks, whereas the older ones were more closely related to this tach, which has white lettering all the way through it appears. And this one appears to be the right one http://cgi.ebay.com/ebaymotors/aw-cgi/ebayISAPI.dll?ViewItem&item=580753721&r=0&t=0 Without being able to compare sizes, not positive, but I bet thats it.

    Not at my truck right now, but I am almost 100% sure that my dad used the needle off the gas gauge on the tach, to replace the "fat" needle on the camaro one.

    There isn't much to the changeover. Unbolt the fuel gauge face from the stuff on the back of it. Unbolt the tach face from the electronics on its back. Glue (black silicone is invisible) the tach gauge to the fuel gauge face. (have to cut the holes for 4wd and brake in the tach I believe first) Rivet (my dad did anyway) the camaro electronics to the now joined tach face/gas face. Done with that. Now again, not sure if any mounts or anything had to be removed from the tach face, but if so, no biggie.

    Going to have to cut a hole in the back of the blue dash piece to get the wires through also I assume. The correct camaro tach will take a seperate plug, and will NOT require any mods to the printed circuit board, (not really a board anyway) for the tach itself. The plug is easy, one wire to the dist. cap, one to the fuse panel (ign. hot) and one to ground, I used the grounding strip (bus bar) thats already under the dash on my '86.

    The only other thing is now you don't have a fuel gauge. I believe from the same camaro, he removed the small gas gauge, and did the same thing, only this time removing the clock. the clock is tied into the printed circuit board, but so is the fuel gauge. Run wires from the correct copper path on the printed circuit board from the original fuel gauge, (be careful soldering the circuit board!) and solder them to the clips that make contact on the back of the clock/gas gauge.

    That should do it, all done : )

    I'm just gonna replace all the guages in mine. I'm to lazy to dig through junk yards [​IMG]. Besides, there aren't many around here....maybe two and they're full of yoters.

    Exactly what I would like in my 90, will have to start diving for those camaros. LOL

    Looks great, do your 33's rub the inner fenders when turning?

    33's don't even get close turning. I've been hitting (as large as i can find) bumps while in various degrees of turning to see if the tires ever find the fenders, but so far no way. The only place they MIGHT rub is when you are not at full lock..the tires are clear of the wheelwell at full lock, but with flexy suspension (not stock, like mine) you might get them to hit.

    Got a set on order today, needed new shoes and your post talked me into the 33-10.50R15's just like yours.

    How much is you Speedo off?

    Re: New pics, \"home made tach\", 33\'s with no lift, hydraulic slave cylinder,etc

    Actually my speedo isn't off a bit lol.

    I have no clue what the donor '76 K5 axle ratio was, (so no clue what the transfer case speedo gears are for) I used an '86 10 bolt with 3.42's, the 33" tires which were never stock, and threw on one of those speedo gear adapters that GM made, also of unknown ratio. I did absolutely no figuring whatsoever on what adapter I might need, since the speedo gears were unknown ratio. The thing is absolutely dead on. 1 mile at 60MPH comes in at 60 seconds! I couldn't have hoped for it to work better!

    You could probably get away with about a 1 tooth different speedo gear, but unfortunately th esite I used to use to figure what gears you need, is no gone, and I have not found a replacement. It told you EXACTLY what gear to use and how to determine which gear you would need. it was a great site
    : (

    When are you going to get the tires? What springs are you running? Stock 2/5 leaf or 3/6 leaf like me? I wouldn't mind comparing ride height with you once you get them, to see if the 2/5 leafs and 3/6 leafs give different heights...they probably SHOULDN'T, but I'd like to confirm!
