I had a driveshaft shop build my driveshaft with Chrome moly weld on ends in 3" diameter x 0.83 wall steel tube also using 1350 u/
js, with my Jerico I had to go with a special hardened front transmission yoke. All very strong etc for my high hp engine.
I asked the driveshaft shop about going chrome moly tube, and he didnt recommend it and said steel driveshaft tube welds better to chrome-moly ends with correct welding rods, and they made a top quality job. The other bonus from dealing with a proper recognised shop is its a compliance requirement for certification for the road.
A friend got a driveshaft done locally and they ground some of the weld off to ends to balance it, I was horrified at the standard of work so went to the driveshaft shop in the big smoke. This chap welded proper little tag weights on, and charged me $239NZ but I supplied all the parts apart from the tube!
