I bought a Strange S60 for my 69 RR vert from Summit with a coupon for 10% off. Buying it that way was the cheapest way to do it. I did plenty of research.

My logic was that the S60 was brand new, came bolt-in ready, and is bullet proof. I'm only running a slightly modified 440 that makes about 430 horses.

I opted for the 3.73 gear, powder coated with perches already mounted, and 11" drum brakes. I also upgraded the diff cover.
I have about 1100 miles on my full resto, and so far, so good.

Did I mention that it looks awesome?!?!?
