Driveshaft results
After months of contemplating, I pulled the trigger on a new aluminum shaft.
The shop also made an aluminum pinion yoke and hard shimmed instead of the stock crush shim.
Smoother, tighter feel, no more slapping on decel/accel.
Noticable increase in engine getting up to speed. Shift light is there much faster. I thought the claims of a half a second ET gain was a fable to sell driveshafts.
I was wrong!
I'm a believer in light drivetrain!
Stock tonnage of driveshaft weighed in at 43 pounds.
Total weight of new driveline is 16.1 lbs complete.
This was a custom local driveshaft maker. Old school veteran car builder. I contemplated mail order, but went with a local shop. The aluminum pinion yoke doubled my cost, but gets away from adaptors. It's debatable whether it was worth it, but I was caught up in the weight savings moment.
If you live in WA state, this guy is the king of drivelines IMO.

$750 for the driveshaft.
I looked at Steeda and a few others and they run in the same price range.
Another $750 to make an aluminum pinion yoke. The labor gets ya.
I wanted to avoid the adapter although I don't think the adapters from the good shaft makers are bad, just wanted a clean setup. (Credit cards are evil.)
What was surprising was the seat of the pants feel. Snappier, revs quicker, tighter, drives better.
I can't vouch for a half second gain, but I can say that there would be a noticable gain.
IMO, worth doing.

2 Methods of swapping driveshafts.
1. Unbolt the driveshaft and use an adapter to bolt to the pinion yoke on the rear end.
2. Replace the pinion yoke with the correct part for the new driveshaft.
