If I remember correctly the 3 holes on the side are 3/8 NPT and the hole on the top front is 1/2 NPT

Are they taper threads or O ring boss straight threads? The pitch is the same but no taper, need to use ORB (o-ring) type AN adapters on these types of thread. That is why you can only get a few threads of an NPT fitting in. Similar to oil cooler adapters from Setrab.Black Boss said:Yep, That's right. The 3/8 threads are on the small side, only got just over 2-3 threads of engagement with the fittings....

All the diff cooling holes on the side of the wattslink diff cover are 3/8 NPT, as mentioned above, and they're not tapered. So, you need to use thread sealer like the instructions mention.
As far as difference in driving feel, all I have to say is... WOW!
It's going to be hard to explain the difference in words, but the rear end feels solid and very predictable. There's a few corners here, in Mexico, that I'd like to do a power slide when no ones around and I no longer get a tank slapper effect towards the end of the slide.
Per Cortex's recommendation, I used the 2nd hole from the top on the diff cover, but I think I may have to go one hole lower, since I lost a little bit of rotation. For now, I softened the stock rear shocks one click (5 to 4) and it felt a little bit better. My plan is to test it out at VIR in a couple of weeks and see which position works best for me with the stock suspension (+ 18mm rear bar).
I do have a question for those that have moved the wattslinks between the different holes. Did you have to re-adjust the links, or the length preset by cortex also worked for the 3rd hole, as well? (The preset lengths on the 2nd hole centered the rear end perfectly).
Overall, I highly recommend this part to anyone out there that tracks their car.

Did you notice any increase in NVH?
I've noticed my gear whine is a bit louder too but hadn't put the two together until now. For me there was no increase in NVH as I already had the Ford Racing panhard bar which added a bit.F.D. Sako said:I noticed a minor increase in gear whine.
My rear end has always been loud, now it's a tad bit louder. It's well worth the investment. It feels like a totally different car.
F.D. Sako said:Just wanted to update on the gear whine increase. Today, for the first time, I went on the highway with the car, and the gear whine is noticeably high, to the point where it's unbearable and hurts my ears.
I'm 100% not everyone will have this problem, because my car whined pretty bad with the stock panhard bar, so it's understandable that the watts link would increase it.
I might have to bring some ear plugs along for the +5hr ride to VIR. then I'll most likely take it to a shop and have the gears re-aligned while they replace the pinion seal.
