M410 / M41 tranny flange interchange 1800

I have a 72 1800ES that needs a new driveline...spline is loose and the ujoints shot. I found a larger diameter driveline from a 1970 1800 equiped with an M410 tranny. To fit this driveline in the ES, I'll have to swap the yolks on the differenetial and the Overdrive output shaft. Is this possible?
Thanks

    Hey Beau!
    It is pretty hard to get them off. Since both use the same OD,
    chances are good. I've never done this though so I can't say for
    sure. I think I would look for a driveline from a 140.

      The 140 drive shafts won't fit - the wheelbase is shorter on the 1800. You might just check on getting the spline replaced at a machine shop. They aren't as expensive as you might think - they just cut out the old and weld in a generic replacement, rebalance. Look in the yellow pages for a machine shop that specializes in drive train modifications (hot rodders are always getting things modified) and take it there for an estimate. I had the driveshaft on my 544 shortened and balanced to fit my OD tranny for only $40.
