Ok Guys...Thanks...I looked at LMC, Ebay, Amazon, etc...etc...I finally found one for a 1987 model F-250, except it has washer fluid & coolant overflow tanks built into one unit. Mine is only one tank for wiper fluid, but the 87 model will fit just right since it has the same mounting tabs as mine...
Cost...$44.95 + tax + $2.95 shipping...I ordered it, only don't know what I will do with coolant overflow part of it as I have a new coolant overflow coming with my new Champion 3 row aluminum radiator. I guess I could run a tube from it and tee it into the washer fluid outlet hose to sprayer for extra wiper fluid capacity...
Thanks again guys..I will be posting my new radiator install and coolant bypass filter soon...
