New or better radiator overflow!
Anyone know where the best source for new OEM style overflow tanks or even better a nice setup for a chrome one or any other options people have done to make it look nicer, (no painted plastic ones). Any pictures would help. Thanks

new OEM stock tanks are still available from GM.... less then $20.
for a diff look, you can get any aftermarket tank... these usually mount to the radiator itself.... some are quite tiny too.
or you can take any tank from another car and figure a way for it to fit and look nice.
also, if you find any water tight nice clean box, you can use it.... so if you find a nice polished SS box, or if its just a empty beer can, you can use it.. lol.
for the stock though just order one thru GM. search and you'll find the part number.
for aftermarket, my local autoparts store has this small rectangular aftermarket one that tucks in under the radiator support nicely. athough our cars look wierd to me IMO without the tanks...
