    I'm a fan of that silver for sure..
    With the 05 GTO 4L65E I had in my 73, I ran both 3.73 and 3.42... Not much difference between the 2, the .73 was a little more fun around town and the .42 slightly better on the road... I'm planning the build for my next one, I'll be going .73 in my 70.

    Have you set the 05 GTO engine in place yet, curious if the front accessory stuff works for you and if yes, what mounts are you using.
    Mine hit the steering gear box, I ended up using Vette accessories.

    If it makes you feel any better about it, DSE subframe connectors are the best on the market in terms of function.
    If you're not too thrilled about cutting up your floor, weld in connectors from global west work pretty well too.

    Or since you’ve got full access to the torque boxes, just make your own from 2x3 11ga tubing.

    Different generation, but I just rebuilt my rear and replaced the open carrier with a Eaton style LSD and 3.73 gears. I love it. Trying to get used to the difference in rpm at certain speeds, but that's only because I have driven this car for 20 years with the same setup. With the stock setup 3rd gear sucked! I would have to hold 2nd until close to the redline. Even then you could still feel the lack of torque until about half way through 3rd gear. With 3.73 gears 3rd pulls just as nicely as the other gears. It realy brought consistency to all 5 gears. Even pulls nicely if I'm cruising in 5th, and give her a goose to pass a slow poke in the left lane without needing to down shift. Realy worth the slightly higher rpms, and little less mpg in my opinion. As it realy improved the acceleration behavior overall.
