Triumph Repair: triumph spitfire rear axle. ?, wire wheels, drive shaft

Question
Hi Jim , i have just brought an old kit car,a marlin roadster, its fitted with a triumph 6 cylinder engine and a solid rear axle which is narrower than the front suspension, i removed the wire wheel and expected to find a bolt on hub , but no such luck what i found was a splined hub with the drive shaft bolted through the middle of it, it is now not possible to simply extend the rear wheel base by simply adding spacers, i have been informed that the axle is possibly morris marina or it could be triumph, could you please advise, best regards steve  

Answer
Steve,

To the best of my knowledge all the Triumphs with wire wheels used a bolt on adapter.   I won't rule out that it could be from an early car (ie Pre- TR2), but I have no experience with the first couple of cars with the Triumph Badge (TR10, Mayflower, 1800 Coupe and Roadster, etc).  

Wire wheel adapter bolted through the middle does sound like the setup MG used, at least on the late 60s MGBs.  Likely the MGAs also, but this is the Triumph expert lounge.   

You might poke around for parts suppliers that have online catalogs with diagrams, you may recognize somethere there.   You'd also do well to clean up the axle as best you can to find any casting marks or part numbers/serial numbers stamped into it.  

Otherwise, not much to go on.   Sorry.


Cheers,

Jim
