i'm building up a '65 mk1, (lo cost rebuild, 1275 ADO16 25000 miles oringal), will the oringal cross joints be ok to use with a tuned 1275 engine? I was after some QH cross joints but i cant find any, Any one out there got any going cheap?

The cross joints are different to hardy spicer joints

The QH joint was an upgrade that turned the original rubber coupling into a Hardy Spicer type U/J but was different from the H/S joints used in the Cooper S and Auto Minis. The QH joints are no longer in production. The middle section of the Q/H joint is a commonly available U/J from the prop shaft of a specific car though so if you can find a second hand set with the Nylon caps in good condition the joint can be easily repaired.

I only have one item to add to Dan's explanation. If the nylon cups are in reasonable shape, you can rebuild the QH joint using the driveshaft u-joint from a Triumph TR4 or TR6. (Driveshaft u-joint... not half-shaft joints as were used on the IRS models). Simply press the old steel cups out of the nylon bits and press in the steel cups from the new u-joint.

EDIT:
Sorry, I forgot to mention... the Hardy-Spicer joints look like a u-joint on a steel flange that attaches to the gearbox. The QH-5000 joints look like a sawed off Celtic cross and fit the "yoke" type outputs on the earlier gearboxes. My car is old enough that it came with the yoke outputs and now has QH-5000 joints. See a picture at:

The steel cup on the right is a racing part from the late 1960s... kind of a beefed up version of the QH-5000's nylon cup. The center image is a TR6 u-joint inserted into a black Delrin cup I machined to mimic the QH-5000 cup. The right-hand image is a traditional QH-5000 with its white nylon cups. As mentioned the QH-5000 is NLA. Mini Mania (and possibly Mini Spares) had their own version for a while that they called a QH-5001 and it had green nylon cups. The only other source I know of for similar parts is Heritage Garage in California. They make a modern reproduction with machined aluminum cups. They are not cheap. They go for about $200 per pair. It's much cheaper to find a rebuildable set and restore them.

QH-9000 ? Is that a typo or is there some version of this joint I haven't heard of yet? I found I got the part number wrong also, it's "QL5000" not "QH-5000"

For the record, you can see pictures of NOS QL5000 joints at these closed (sorry) eBay auctions. Use eBay's "advanced search" for items 230179343479 and 170157905980.

MiniMania still has pictures of the QL5001 (green cup) u-joints but they are NLA and "superseded" by the original rubber coated u-joint.

Typo, and a bad one at that.
QL5000 is correct - sorry!
