gas tank

[mtandrews]

saw in an old classic chevy truck magazine a 68 pickup with a gas tank out of a buick. thats all it said in the mag. buick what??? regal, 225, front or rear drive?? a few months later a 70 with the same thing, same mag, but now tank is from an olds. Is this a good old boy secret or an oversight by the mag assuming that all classic chevy truck guys know what the donor vehicle is. I know that there are a couple of aftermarket sources where you can spend $299++ for a kit but what about us poorboys. there is a junkyard here in san antonio that sells gas tanks complete with mounting straps and sending unit all day for $30 but you pull it, you bought it. guessing can get real expensive real fast. does anyone out there know anything about this or know what vehicles' tank fits in between the rails where the spare goes. any help/info will be greatly appreciated because a big block goes through a stock 14 gallon tank faster than you can say cinco de mayo!! mtandrews@hotmail.com
