Asking price?

I have three items I may try to sell. Need some idea of a fair asking price.

20ft. x4ft. Budwiser/NHRA banner. In original box from 2005 season. Has been out of the box about four times. Never put up.

Hooker Headers #5902. Will need GOOOD sanblasting. Appl.: Dodge PU about 71 - 91 with small block.

SK (SK Wayne) Combination wrench set from late 60's - early 70's. 3/8" to 1 1/4". Good shape. Soft case (roll up) in very good shape for age. The 15/16" is missing.

What to you folks think?
Thanks for the help.
Mike
