I have driven My '63 +4-4Str literally all over the world. Clutch was converted to a diaphragm in 1999. Bell housing relined by prior owner. It uses a carbon thrust bearing. You need a good parking brake to hold the car with something other than the clutch. Because of the harpoon on the back of the axle (ready to puncture fuel tank) I converted to a MGB cable system. Keep the rears adjusted and save the clutch. The worst experience I have had was at LeMans getting to the Morgan Parking Lot. Very slow and uphill. I could smell the clutch. But it did not ruin the clutch and it must have well over 100,000 miles on it. After LeMans My +4 was shipped to Boston and We drove it across Northern US back to Seattle. After this a trip to the Rocky's. Clutch still doing its job.
