Aluminum swing arm for RD400F

[2 Smoker]

Not to beat a dead topic, but expanding on what Bitzz said.  Regarding a non-F 400 DG swinger, I've had one on my 350 for years. 
Details you need to know: 
- a 400 DG is 2" longer over stock from a 350.
- it's almost plug and play.
- a kind member here machined a cool extender for the rear fender, so it arches properly.
- the longer geometry hasn't affected handling that I can tell, other than make me work a bit more throttle for wheelies.
- a machinist friend made me several of the right side bushings needed to fit the 350 axle in the 400 swingarm slot.  I thought it may be a wear item but in years, it's never needed replacement SO if anyone wants to mate a 400 swingarm to their 350, I could provide the needed bushing.  The fender extension would still need to be dealt with.

LMK.

Ahhh they beauty of it
