i have a friend who restored 3 70's yamaha DT400 enduro bukes.
he just got a smoking deal on 4 DT80 bikes. he plans on using 4 to build 3.

he bought all the cosmetic exterior parts new or almost new on ebay in the last couple of weeks.
he gave me 3 NEW gas tanks to paint. and 2 new and 1 almost new side tanks 2 sets will be blue for the 74 model year. and 1 will be silver.
he said they have been listed for months on end with no buyers. he mads low ball offers and sellers were happy to accept.
