Radiator.
The radiator looks solid and intact but it could use refurbishing inside and out. So two questions:
Is refurbishing an option? I have enquired about repairs with other vehicles and the cost usually has me purchasing a new one instead.
Which brings me to the second question. Are new radiators available for these for/from other applications?

Paint.
I would like to start painting those parts I've repaired. Is there any way to source the Khaki colour used during manufacture in 1944? There are some places the colour still exists on my truck but they are either not removable or too small to use for computer colour matching... paint shops don't seem to have people who know how to match colours without the aid of a 50,000 dollar machine.
I'm hoping someone has a paint code 'close enough'. I'm considering purchasing Tamiya's Khaki model product and painting a blank then having a paint shop colur match that.
