P.S. I have borrowed a pair of sills from a bit closer, thanks anyway thanks Commerjules, yep it looks like the only way at moment , trouble is keeping the wheel flanges moving together while looking at the prop flange , turn the prop flange , one or the other wheel flange turns on its own , bit like one of those puzzles they give chimps to work out , three days later still cant work it out, thanks Martin, i dont no weather the sailsbury or Chrysler are marked any different, the axles i have are pretty rusted , found makers serial number , a casting number nothing else . At the factory they probably just used a sticker or painted on numbers, that came off first winter. in the mean time ill just keep turning the flanges , still cant work it out !
