I have 1997 Robin Hood S7 with a monocoque chassis, 2.0 ltr pinto with a 4 speed gearbox, everything was fine until the other night while travelling at about 70mph the was a horrible vibration for 5 seconds then a Big Bang from the tunnel, the next thing I could feel the propshaft repeatedly whacking me leg after it had smashed my fibreglass seat, the front joint is a rubber doughnut type and it had fallen apart.
As the tunnel is ripped and bent on both side and the top and the floor I have cut a hole to inspect, I have removed the prop and it has a 3 bolt flange on it to bolt the doughnut to, but the bit thats still in the gearbox just seems to have a few bits of rubber left and nowhere to fix a new doughnut to, Ive looked on eBay and the doughnuts seem to have 6 holes, (3 for each flange)
My question is, were there different types of doughnuts on different years or is the difference between 4 speed or 5 speed. I think the engine and box were from a 1979 cortina but it has the Sierra rear suspension and diff, any advice would be appreciated, would I be better off getting a new prop made with proper u.js both ends ?
