I am going to put the 3.55 in with a semi-regular engine (as soon as all my parts show up).

OK, I haven't got quite all my parts yet, but I thought I would do an update on the install.

The bolts holding the unit together were of various torques. Some super tight and some easy off. Pulled them out and re-torqued with thread lock.

2. Definitely replace the spring washers. Here's how mine came;

Brand new unit and they were ALREADY broken, hehe. Got the washers from rbryant on here. Simple to get to, and put back in.

3. You either have to bevel the clip on the inner axle shaft, or leave it out entirely (I'm leaving mine out). Even though it looks like they beveled the gear enough (where the axle snaps in). I found out the hard way they didn't.

Not to worry, 20 tons of pressure does this;

I tore the end of the spline off of it with the clip, lol.

4. After you press the bearings on you then have to "fit" the inner stub axle (I just used a junker stub to do my fitting). You may find that the stub will not go in after you press those on (which I did). You must then bore out the hole a little bit to clearance it. I used a brake hone.

The stub etc.;

Honing it out;

Fit after hone;

I spun the stub axle around in different directions just to be sure of the clocking. No problems.

Oh yeah, one more thing. I had to "clearance" the tabs on the speedo gear so it would snap on. If you look at this pic you will see an old one (on the right) and the new OBX. Notice the tabs;

It seems that we have to do the quality control for them. BUT I'm still OK with these as long as they work. The labor is minimal compared to the cost of the Quaife. I can "massage" a part to work. I can't cast and generate one.

Oh and for those that don't know, there is a write up in the wiki for the springs;
