Cross Reference for 996 TT Flex Disc aka Guibo?
Cross Reference for 996 TT Flex Disc aka Guibo?
I've been trying to reach KO Motorsports to purchase a Flex Disc / driveshaft coupler / Guibo, no response.

Has anybody been able to cross reference this part to another application like BMW, Alfa, VW, Mercedes, Dodge, etc. that could be ordered from a regular auto parts house?
Looks like there might be a fit in here somewhere:

It appears to be a Lemforder part judging by the part #'s on the disc. GAP01-002 & x133-0317. Can anybody source these or X -Ref by these part #'s.
Dimensions :
bolt hole 10mm
bolt diameter 78mm

BINGO!! It's actually a SGF part...
No x ref, at least from SGF, it is literally a Porsche specific application.

Just found out that Vertex actually stocks the same 996 flex disc for around $100.
...but they don't advertise it since... "we'd rather sell the complete driveshaft..."
This part may be considered when doing a transmission mount / bushing replacement, as you already have a lot of stuff out of the way and most of them are likely deteriorating due to age and/or use.

2 of the BMW flex discs (GAB01-009 and GAB01-015) are "in the ball park", but they're 5 mm too thick / deep (28mm vs 23mm). Same for the Opel flex disc (GAO-15).
The GAP01-002 flex disc is Porsche 996 dimension specific. See chart below:

The correct disc is readily available (at least for now) and cheap ($59). Why mess around with something that is not correct if you don't have to?

Coupler?

Did you install the coupler and did it eliminate any kind of slop in the drive line?

Yes, it's installed. I really didn't notice any drive live slop before installation or any difference after installation. I have the X73 suspension on my Turbo, if that makes any difference. My transmission mount was completely shot and I replaced it with the Cantrell Street Urethane bushings. I have noticed a very slight increase in NVH after everything was installed.
Couple of installation tips:
You need to drop the nose of the transmission down (while supporting the trans housing) and push the drive shaft forward to allow for the trans output flange shaft stub to clear the shaft flange and coupling.
You need to hold the front drive shaft to loosen or tighten the allen bolts on the shaft side of the flange. I used a large round round jawed Vice Grip to hold the shaft. You could also use something like a pipe wrench. See pic below.
When installing the new coupling, you need to install the allen bolts on the front drive shaft flange side first (while holding the shaft as above).
After inserting the output stub back into the shaft flange, the trans then needs to be brought back level and in neutral to allow shaft rotation to initially insert hex bolts on the trans side, then engaging & disengaging the parking brake while rotating the shaft to tighten up the hex bolts.

Thanks for the quick response and the pictures.

[QUOTE=rsvmiller;4371567]Bump to this thread guys!
I am putting my 997tt back together after some extensive works, I bought this 997 febi guibo and compared it to the old one, seemed the same, so chucked the old one away...
Now I am actually onto rebuild I find that the fit is not perfect as with the OEM one. It has a gap between the metal sleeve and the locating machined hole in the tranny output. The only way to close it is bolt it up then it slightly distorts the Guibo...
Not good and I am thoroughly p*ssed off with the car at the minute lol
So does anyone know where I can get the GAP01-002 part from? Has anyone else had a fitment issue with the Febi? DO I have the wrong Febi part maybe? Can anyone confirm febi and gap dimensions are the same or slightly different?many thanks

This is the one I had installed by my local indy, they reported no issues to me.
