Mark, how much would you charge for the machine work to make it fit the getrag?

Im creating a getrag setup.
My part are getting machined right now.
Its a 1/4" S/S bracket that attaches in 3 places.
And a pillow block with a 6206 bearing in a chamfered housing.
Should have installed pictures next week sometime.

$40 or so. Its not that much work but the setup is a pain in the ass. If you want me to do it just send me the bearing housing.

I know it's intended to cancel torque steer but would this modification help wheel hop?

No, wheel hop is a permanent result from hard sidewalls of street tires, the only way to get rid of it is to never spin the tires. For most of us this means slicks.

No there are ways to virtually eliminate wheel hop. Launching at the correct speed is one. You can also get rid of alot of it by upgrading to polyurethane suspension bushings and engine/tranny mounts. An LSD or insert and the right tires help phenomenally. Also having some types of aftermarket struts/springs factors into that too. I don't wheel hop in my car, havent in years with over 50 passes down the track.

Ok I got my setup completed.
Questions and comments welcome.
This is on the 2200 motor, and completely bolt on.
Worst car scenerio is you need to clean up the tapped holes due to rust on the block.

I made a completly new bracket and bearing block.

Nice job man... looks good... Where did you get that piece made at?

Don't forget to trim the engine cradle too... if you use Axles that are close to or larger than the stock GM inboard joints the tripod cups will contact the cradle so long as the bracket was made right.

I connected the automatic axle last night, and I have about .25-.50 clearance between the engine cradle.
I may have already modified it a long time ago for another reason, but im not sure
I was initially worried about the exhaust, but I have a good amount of clearance there.

The flat mounting bracket, I made, but the pillow block is a purchased component from MISUMI.
It is a configurable piece, which means you give them the dim's and they create it just like a catalog item.
Its electroplated, with a dual sheilded bearing, and a S/S retaining ring.

This is the initial concept paper bracket, just to show how it hooked up to the block.
All the M10 X 1.50 holes exist already.

What kind of spacer did you end up using at that top lug?

I didnt need one on the top bolt, it was needed on the left most bolt.
Actually a 1/4" npt half coupling worked out perfectly behind the bracket.

Oh thats right, forgot which one it was...

Good stuff, I ended up welding a short section of 1/2 tube I cut on the lathe to the backside of the panel.

I have my jackshaft now (Thanks Brian)

Still confused on a couple of things.

1. I can get a regular output shaft seal from a manual or auto right?
2. Bearing part number for the cast shaft is.......?
3. And to make this fit the f23, the mounting holes have to be slotted right?
4. Im going from auto to manual and still have my auto axles. Which of those axles can I re-use for the manual?

Yes for Number 1...
Not sure on part number, take old one to a napa...
not sure if it will fit on an ld9 or eco with F23... I modded mine as did others for their use.
You can use either side, the auto sides are both identical... both of them can be used on the passenger side with the jackshaft... you will still need a manual drivers side.

2. Bearing part number for the cast shaft is.......? Not sure I would have to look it up
3. And to make this fit the f23, the mounting holes have to be slotted right? Yes, you have to slot and clearance the holes. They have to be pretty accurate, if not you caus cause big problems.
4. Im going from auto to manual and still have my auto axles. Which of those axles can I re-use for the manual? Auto axles should work on both sides. I am not 100% sure on the drivers side that might need to be a manual.

Thanks guys.

I found that my auto axles work with this manual tranny+ jackshaft. I will wait until i get the engine and tranny in car to see how much clearance needs to be taking out to bolt to the block. I may just ship the bearing part to you OEM. I just want to see what Im working with first.

Neither of the original bracket will even come close to fitting on the Getrag.
A custom bracket is a must.
See above.
Either modify the original, or create a custom new one.
Re: Intermediate / Jack Shaft

It's only a must if you're putting a Quad/LD9 Jack Shaft on a 2.2/2200ohv or V6. Otherwise if it's just going into a Quad/LD9 w/ F23, you slot the holes slightly or shorten the input on the jack shaft a touch (I believe that's what Chris said he did with his).

I believe the Jack Shaft was used on 2.2OHV's as well, so if you picked up the correct one for your application, should be damn near a bolt on.
