ok cases apart without any more issues with bolts
think apart from bent shaft i may have got away "lucky"?
no apparent damage to gears which look in pretty ok condition
one bit floating about in there and a blown seal

any chance of a link to the ebay part pls?
i cant seem to search or locate US parts from UK

Now that you have it out, have you checked to be sure it's bent?  With the bearing blown to bits, it might have been hard to tell.  (I know, wishful thinking...  but stranger things have happened.)

Almost certainly the damage was done with the kickstart from the looks of it so I'd check those three gears very carefully.

was thinking the same 
have the new needle bearing, the kick and idle gear so could possibly offer up to see 
or presume may have to take to bits to see if it is without gears on it 

 

eBay item # 195599724735

D&K have a complete DT175 gearbox on ebay for £74.

Taking into account shipping charges from the US, it might be cheaper to buy that, and sell what you don't need?

I have TY175 output shafts, but they are probably different to DT.

Again, 1976 is a unicorn.  If you have a 1976 DT175c (559 VIN prefix) many of the transmission parts are "one year only" in the USA.

Though 1976 and later Euro twin shock bikes (Euro "F" model, not related to the US model naming letter scheme) could be the same.

shaft doesn't look quite so bad now new needle bearing offered up but still has a wobble i think whether that's it moving in the case or actually has a bend its hard to say
i will change out if i can find one
thanks for the links i will look at them now
one thing that is a problem is

some damage to the bearing housing, not cracked but the damage has deformed the housing
anyone have a good idea to pack it out?
JB weld or is that swearing on these forums?
have a few fabricators in area i could ask to do it i guess

See how much material around the outside of the bearing housing, and see it if it would be possible to machine the housing bigger, and fit a sleeve with the same ID as bearing OD.

yes thats a possibility 
or find a crankcase replacement  i guess
