I"m in the process of swapping a 2008 C6 Z06 TR6060 and differential into my 2001 C5. I am using a C6 cradle, C6 lower arms, and a C6 rear spring with RKt56 offset mounts. I have an interference issue with the diff cooler feed line on the lower portion of the differential. I want to keep the stock differential cooler pump, and was wondering if anyone ever plugged the lower line, then drilled and tapped the side of that same fitting boss?

To answer my own question. The fitting supply shop suggested I have a -6 fitting welded to the boss, then drill through the -6 fitting to get my oil supply. Seems like a reasonable solution to the clearance problem while maintaining the differential cooler.
What's it interfering with?
I've seen it hit the spring until the car is set down on the ground and then the spring moves downward, providing the needed clearance.
My 07' stuff hits the spring Like Bret said, but I also had to grind some of the cradle to clear that oil fitting if I remember. I'd have to take a look again, but it wasn't much grinding.

It's hitting the spring, which is not a big deal if it clears when the weight of the car flexes the spring down. The problem is when the car is on a lift for service, or in my case when trying to install everything with the drivetrain removed. I think welding the fitting on is a good idea, and while I'm welding I can just weld the bottom closed since I can just unfasten the -6 connection for draining of the differential fluid. If you see a problem with my logic on this, then please advise. I know the 2009 and up diff has the boss cast into the diff at a 90 angle from where it is on my 2008 differential.

I have already done the minor grinding on the cradle.
should work just fine, and make the maint a bit easier
I'm looking to do this swap, I have the c6 cradle and suspension
do you need different offset tires staying with the c6 suspension?
It's my understanding the wheel offsets don't need to change for proper fitment, but the wheel is moved slightly toward the rear from the original position.
I wish I would have measure the wheel location stock and with my 07' stuff. I always hear different things, but moving back helps my rubbing some. I also hear that a 28" tire will not work with this setup or be super close, but haven't tried it yet.
Any idea what the issues are in relation to a 28" tall tire? I fit the Hoosier 17 inch slick without any issues using the C5 drivetrain and my car was lowered.
What are the issues with using the C6 stuff? I have to have a 28" tall tire to make this build work on the track.
1. Why run a diff Heat Exchanger? What exactly do the temps run at highway cruise with and without the H.E.?
2. Most will remove the H.E. and plug the side cover, use a stock rear C5 diff cover for over axle pipe clearance.
I've only done a couple of the C6 30 spline Z06/ZR1 trans swaps into the C5's.
Bret helped me out with the details of the swap, there is a section of the cradle that needs to ground down when using the swap mounts, doing that now will save you a lot of time.

I will not be using the factory HX for the diff. I've never personally measured differential temps, but several road racers have. They claim it can overheat and destroy the differential, and I plan to take this car on the road course. With the TR6060 swap I now have the capability to use transmission and differential coolers, and it seems like a good idea that won't cost much to accomplish.
I run 28's on my ride without issue, other than rubbing the liners above the tire, (which I've consequently resolved). I actually like the altered position of the wheels.
What happens to the factory diff cooler? Does the heat cause it to open and allow trans fluid into the diff or what?

If you thing welding a bung there is doable, then great.
Otherwise maybe loose the spring & go coilover's, since you want to road race
I don't plan to "race" the car on the road course. I just want to run 20-30 minute HPDE sessions, that's why I want to keep the cost down, and use stock suspension. Plus I don't have enough chassis setup experience to make sure my coil over setup is working correctly. It's like anything else, it's a snowball effect. You put on coil overs and sticky tires then you have to reinforce something else.
