Another Mag to Spokes question - Hub and damper

78kz650b, had 16in mag and 19in mag from the previous owner. I got a great looking set of 18in/19in spokes off ebay. The front monted just fine.

The rear I wil need a new axle (on the way), but the hub and damper won't transfer over to the spoke wheels. The one from the 16in mag is much bigger and beefier, like 4mm all the way around.

Does anyone have a hub and damper from the 18in spoke rear, or can you guys point me in the direction of which to buy? I'm not sure if the spokes came off a B, C, D, what year, etc. so I'm not sure what to look for on ebay. Also some sellers aren't exactly sure, and I don't want to deal with shipping stuff back when it comes and it's from a 16in mag or something.

Thanks!
The bike looks 100x better even with just the front on, so I cant wait to get the rear together.

I had the same problem but going the other way. I got in contact with a seller on ebay who goes by sudmanracing1 who got me straight the first time. You might be able to get hold of him through ebay. It's worth a shot.

needs a new rear axle? have you tried swapping your rear wheel bearings from your old wheel to the new wheel?
front wheel and axle are same on 650/900/1000 up to 80 anyway,900/1000 have a bigger rear axle and bearings than 650.

Test I'll try to get a hold of that guy, thanks!

And wire, maybe the previous owner had 1k wheels on it or something but the axle is bigger. I've got smaller ones coming and a swingarm to accommodate the smaller axle diameter, but my main problem is the hub being so big from the 16in rear.

you might be able to just swap bearings between wheels
