Went chasing yesterday to fix the shaft issue I finally ended up with. A variety of information ensued, mostly conflicting with each other between manufacturers of parts and the people who use said parts to build assemblies. I have also amassed a list of different numbers for the unis and centre balls.
Hardy Spicer's info: The std uni is a 1300, available in greasable and non-greasable. A 1310 won't fit as while the cap sizes are the same the cross is slightly wider and the caps will not fit inside the circlips. The std unis are about $45-. The centre ball is approx $80-.
A "first stage" upgrade would be to build a new shaft for 1310's, the biggest uni that a flange is available for to suit the Rover transfer flange. Costing approx $60- per uni plus larger double cardan assembly, centre ball & welding, balancing etc. Approx $480-
A "Ultimate" upgrade consists of a 1310 upgrade at the diff end plus a 25R double cardan at the transfer end. This is a Toyota joint with massive unis and a specially made flange for the transfer end. The 25R joint is approx $460- plus $60- for the 1310 uni plus assy and balancing. Approx total $900-.
Metropolitan Driveshafts: Same info re sizing of the 1300/1310 joints. Have data showing that the greasable 1300/1310 are weaker than the non-greasble options (but couldn't write down data). Dearer on the parts but would gladly reco a std shaft from outside parts. Approx $250- or $370- for overhaul with their unis plus $175- for centre ball. Important to note that they picked up that one of my caps was loose in the yoke, dismantled to demonstrate and noted that they would need to shrink and ream it back to shape/size. HS only said "It's stuffed, need new yoke assy welded onto the shaft and matching flange, nah they have to be a set" (of course diff end not the DC that needs doing anyway) and it's also the shaft side so I couldn't get away with only the flange replacement.
Their first upgrade would be a 1310 as again it's the largest that fits the Rover transfer flange. Approx $550-
Best upgrade interestingly was to go to a "Cornay" joint with an adaptor flange at the transfer end. They don't have the 25R joint as the Rover flange is unique to HS. The cornay joint is $2000-.

At the end of all discussions I presented the data and all info I could print out on the Tom Woods shafts and the pricing. Their was unanimous agreement that neither Spicers or Metro could match the strength or the angles of the joints (without going to extremes) and certainly not for the price. They both said go for the Woods shaft.
