Flathead on the Brain

Can't wait to get going on my Flathead. This will be the first year in five years I think I am not pulling either of my bikes apart to redo. They both are done for now and I will winterize the Ironhead and keep the Shovel in running status for the days it may be warm enough for a ride. So I have a few customer bikes to work on over the cold months and other then that I am gonna slave away on the 51. List of shit I am gonna do.
 3 inch dropped axle
Flathead swap
Sand body again
Figure out what color to paint it.
Clean the inside up
Take out a few rear springs.
Box the entire front of the frame. 
New brake lines everywhere.
