WTB: Overflow reservoir CAP

[NismoDan]

Yea, I just bought one of these and magically it disappeared.
All i need is the radiator overflow reservoir tank CAP, the yellow thing.

Please help me out.

Thanks!

Rumor has it that the cap off a Mylanta bottle should fit....buuuuutttt...I've never tried it sooooooo I wouldn't know if it would work or not!

Why do you just hit a 99¢ cent store & find one that fits? All you have to do is measure the diameter of the reservior tank & find something that fits.
