Thanks very much 1200Rallycar and Dodgeman - excellent info !!!
My H190 appears to have about a 4.6 :1 ratio so it will be a hillclimb special !! Will look for something around 4.1 : 1 (Bluebird 4 speed wagon you say ?) Yes, the Bluebird discs look like a bolt up once the backing plates are changed. Interestingly, inspired by your comments I placed an old axle from my coupe (H 145) next to the Bluebird and tried one of the 1200 shims on it. Lines up spot on. Axle dia for bearing mount measures identical as does the bearing retainer collett. Only issue to determine will be the setback comparison between axle flange and bearing. A machined spacer should rectify any discrepancy. If all went well, I could see a possability of a fairly easy fit up. I will keep you all posted with the outcome. Would like also to track down a 5 speed for the A14 - thought I saw one offered a little while back ? Let me know if it is still out there. (no use shortening a tailshaft for the H190 and run it with a 1200 4 speed !!! Cheers for now ... EDIT - My 13" wheels fit over both front and rear brake setups ! (very little clearence on rear - about 2.5mm but that's without any grinding or cutting)
