    Thinking out loud.

    I could replace the midplate, but if you look closely at the case, you'll see the counter-shaft bore is oblong - which means a new case too. Believe it or not, these are very popular and parts are available, new, for them... including upgrades.

    I'm pretty sure my Right Stuff tempenant (or permanary?) fix will hold until winter but the writing is on the wall... so what to chose - so far these seem to be the choices.

    1) Doug Nash 5 speed ($3600)
    2) New Super t-10 with upgrades ($2500)
    3) fix and pray ($1000)
    4) TKX at $3500
    5) T56 - $2500 (found one for that with all the upgrades)

    1) - complaints about clunky and a pain when cold - not just that but supply is questionable... that said, probably the least expensive option that will handle what I dish out.
    2) - highest rating I've found is 325 ft lbs -though rumor is they can handle more....
    3) cheapest - and it leaves me with a spare or sellable trans
    4) they can't seem to come up with a price, but I think if I do this one, I'll spend the 'extra' and get the one rated to 900 ft. lbs (stock is 600)
    5) requires replacement of my bellhousing so could be the most expensive (and could require hydraulic clutch change)..Could also be the cheapest, but it never works that way for me....

    the tl;dr is I think the mid-plate is cracked... but I'm going to run it
    so
    they say you should pull the main shaft out to pull the midplate....
    no, you don't


    the came a gasket search. I'm not convinced the rebuilder made a mistake - granted, the gasket he used was leaking - but still, there's probably a crack here somewhere


    more gasket fun



    somewhere on here

    see the dirty blank spaces? those were both sealed and clean 300 miles ago

    then there was the moment Luigi was laying at my feet while I dropped a gasket sealant brush on him.... oops

    replaced the bushings while I was at it



    back in and leaking.... we won't talk about how it's sealed now

    in other news, I can now use my laptop to program the Sniper


    and in still other news

    trans oil leak. Yeah, I get it, I can always just add lube AND the level will never get to critical... but still.

    driveshaft out

    new seal kit

    trans out

    bright side is there is no oil on the inside of the bellhousing

    it might be that just the tail housing gasket was leaking, and yes, it's a lot more work to do it right


    so sue me. The other side of that story is the counter-shaft may be loosening in its bore. Now, I can 'just' replace the case. Let it go long enough and it'll destroy everything

    yes dear-- i know the heads exhaust port aint round. but the PIPE (header tube) is......
    long header bolts will do it too--but if it persists, try a round port gasket. its worked
    great for me for decades.

    this post makes little sense without another post done elsewhere

    In wheel searching... I came across this at https://support.apexraceparts.com/hc...ment-Guide#htr

    Wheels

    Front: 18x11" ET38 // Rear: 19x12.5” ET55
    Available in: SM-10
    Popular Fitment
    Tires

    APEX Staff Pick: Front 315/30-18 // Rear 325/30-19
    A minimum of -2 front and -1.5 rear camber suggested
    Extreme Performance Summer: Continental Extremecontact Force (200 TW)
    R-Compound: Nitto NT01 (100TW), Toyo R888R (100TW), Nankang AR-1 (100TW)
    Semi-Slick: Hoosier A7 (40TW), Hoosier R7 (40TW)
    Wider Alternative: Front 315/30-18 // Rear 345/30-19
    A minimum of -2 front and -1.5 rear camber suggested
    Extreme Performance Summer: Continental Extremecontact Force (200 TW)
    R-Compound: No options currently available
    Semi-Slick: Hoosier A7 (40TW), Hoosier R7 (40TW)
    Narrower Alternative: Front 295/30-18 // Rear 325/30-19
    A minimum of -2 front and -1.5 rear camber suggested

    R-Compound: Pirelli Trofeo R (60 TW), Nankang AR-1 (100 TW)
    Semi-Slick: Hoosier A7 (40TW), Hoosier R7 (40TW)

    not sure I can stuff a 315 under the front but maybe a 295?

    Another thing, I need to find some C7 flares.... maybe that would be the best way to get the tire/wheel I want under the car....
    Currently, I think I'm -1.5 degrees front and maybe -1.0 rear.... now I've got to check


    Okay quote and what is right now.
    -1.1 F camber
    -.9 rear

    .30* TO (or 1/8" TO)

    I was asked to measure steering angle.

    all at 25*
    3/4" TO
    3.6 degrees (I think)
    -1.75 camber inside
    -1.375 camber outside

    I sound 'smart' but the terms come from this article
    https://ismasupers.com/downloads/tec...steering-4.pdf

    pretty pictures

    round port gasket not a 2-1/8" or 2-1/4"....

    shop full of C3s

    time to fix an exhaust leak

    guaranteed.... just like the last one


    also did some fixes on the cooling system.
    about the trans
    it was overfull


    which could be the leak... I'll know tomorrow...

    PS C3
    it's getting a rear suspension... the old one was VERY worn out... so it's getting a full upgrade



    then a motor.... then a front coil-over...

    We need a "Bummer Dude" button alongside the "Like" button. But good you found the leak and hopefully a little tightening will fix it.

    Nothing is so annoying as reserving 3 hours to drive 1 1/2 hours then realizing at hour 3 that you're not half way there.

    HOWEVER.

    I got home, unloaded my car and saw a huge oil slick where the trans continues to leak. Probably would have blown it up at the track - so I guess I dodged a bullet, but still annoyed that I missed yet another opportunity to race.
