hey,dodgeman,how you doing.a friend of mine called grant (the one that made the throttle linkage)fitted a h150 diff into a h145 housing in his 1200 sedan a couple of years ago.being the methodical little bugger he is,he found he needed a 2 mm plate to go between the housing & the centre to get the axle & the splines lined up.by the way,that sunny wagon ratio,was it for a14 powered wagons as well,cause there's one of those at rushes,& it might be worth looking at.oh,well,maybe i'll do that this afternoon,instead of vegging out.will let you know.
