Sun Visor Needed for a 2000 Trooper

The spring that keeps the driver's side sun visor in place when flipped up has weakened to the point that it won't hold the visor up. I put some velcro on it last night, but would like to fix it right or replace it.

Anyone know where I could get one? I tried a goggle search but came up emptyhanded. Can the spring itself be replaced or must the whole visor?

Thanks much and Happy New Year!
