Good morning, I chose to go with the 2:76 gear. So far I am happy with it. I took the car out yesterday to get chili dogs for lunch and am very pleased with it on the freeway, but the poor brake system seems to be amplified due to increased comfortable speeds. The car is more of a pig in town as suspected, however. I did the gear swap with a good friend last Tuesday night (last week). We finished at about midnight just as a huge storm came in. It's a long story, but I ended up driving the car home (almost 30 miles) in one of the hardest thunderstorms I have ever seen. I heard in some places, 3 1/2 inches of rain fell. I'm happy to say that the 47 year old car drove well in this rain and I motored home at close to normal cruising speeds (except when hydroplaning) when most other vehicles, including 18 wheelers were seeking shelter under over passes. I made it home in time to join the family in the basement due to tornado warnings. Then the power went out for about 14 hours. I like to think I don't own any trailer queens and put the cars in real world situations, but this was one I don't need to repeat anytime soon. My only complaints are the disfunctional windshield wipers and defroster as well as windows that don't seal very well. Off to the next challenge.

I know there were 2 different U-joints, and if I remember correctly, the differences were very big/large. As I measure the yokes on the units I have, I am coming up with a slightly larger (1/8" over length) yoke on the 742 casings than on the 489 casings. The diameter of the u-joint receptacle appears to be the same on both. Although I haven't been under the G yet, I think it has a 985 casing which I think is the same as what I have mentioned previously. Does this sound close enough that I could swap without changing yokes? Are the differences in u-joints large enough that it would be hugely apparent? I am looking at the 2.76 vs. 3:23 more for highway driveability vs. mileage. I may be in Western states where speeding isn't a capital crime as it is in Ohio. If I go with the 2:76's, I will change back to 3:23 upon return home. Finally, does cast iron get heavier over the years? These things are nasty, I don't remember them being this heavy 20 years ago.

But, I also just remembered that I have a 2:76 sure grip as well. I am looking at a long road trip this summer and am thinking about the 2:76 instead of the 3:23. Anyone with an F or G ever tried running these gears? I assume it will make the car an even bigger turd in town, but the highway might be nice. Any experience out there? I'll skip over the 4:88's for this swap.
