+ for you. Thanks for the info.

No, it isn't.

At a cost of $18, the part listed (12085498) is a pigtail, not a bare connector.

quote Originally posted by fieroguru: From the pic above with an angle across the bellhousing surface, the face of the throwout bearing is 2 3/8" deep inside the tranny. You need to verify that the pressure plate fingers have about 1/8" to 3/16" clearance to the thowout bearing (as the clutch wears, the fingers will move towards the tranny - so you need room to allow for clutch wear), so they would need to protrude from the engine bellhousing flange by 2 3/16 to 2 1/4". Use a ruler across the pressure plate and measure the distance from the engine bellhousing surface. On Archie SBC cars, a spacer will be needed on the backside of the throwout bearing to close this gap to the 3/16-1/8" clearance - if not you will over extend the throwout bearing, it will come apart and you will be buying another - I learned the hard way! These trannys were FWD GM with the 3.1 V6 - Cavalier, Beretta, Corsica, etc (there are also Quad 4 versions with different bellhousings). Not all have the hydraulic throwout bearings, some still have the internal clutch lever like the 89-91 tranys. There are also 95+ versions of the Isuzu transmission that are very similar with the hydraulic throwout bearing as well as the later model getrags. Yes, a Fiero spec 2+, 3 and 3+ have all been used with this setup. If you order a clutch, order the Fiero V6 one or it will be $100+ more expensive due to spec supplying the hydraulic throwout bearing which you might already have.

Guru,
I plan to use a 94 Getrag 282 in my LS3 swap. Archie will be doing it in a few weeks. I noticed from the post above, that you mention; ("On Archie SBC cars, a spacer will be needed on the backside of the throwout bearing to close this gap to the 3/16-1/8" clearance "). Do you have any additional data on this. Pictures, size, who made it. I'm trying to gather all the parts needed for this swap, and want to be sure Archie and his crew have this "spacer" so when the motor and trans get there, he will be ready.

thanks in advance.

The stock application had the clutch surface about .81 - .83" from the bellhousing surface, so measure the distance from the adapter plate to the clutch face on the LS(x) kit and subtract it from .81" to get the approximate thickness of the needed spacer (and you might not need one... never worked on an Archie LS(x) kit before). The spacers are just an aluminum ring and slide behind the HTOB, I might have a picture somewhere. I also like to put a spacer between the backside of the HTOB and the face of the input bearing as well (it is pressed in from the bellhousing side and I had one walk out of the case on a high mileage tranny before I started adding that spacer).

Thanks Guru

For fieroguru's HTOB spacer, here's a post of what he did on the F40:

The F40 one is much more involved and has a physical limit on how thick the spacer can be before you much seperate the seal from the HTOB assy (tapered input shaft). The last one I did for the getrag might have started life as a wheel centering ring and was just a basic round ring that was held in place with some RTV. The HTOB just slides into place over the top of the spacer.

even if it wasn't bro, you can just change yoru IP divisor to "1" and set your pulse to 4000 rather than 24000, you get the same result...adjusting slightly for tire size of course
