Removed carpet and seats,found drivers side front floor pan definately needs to be replaced.Also found the rear drivers side and passengers side have slight surface rust and a total of three small pin hloes.Dont mind spending the money for a new floor pan, but havent done this type of repair before.I have a mig welder and really dont want to takle more than i need to.Why couldnt i replace the front drivers side floor pan,and repair small holes and por 15 the floor.Any advice would be greatly appreciated.

HERE is my 2 cents. I found the exact same thing last year. Upon further investigation found out I needed more then I thought. I am in the process of a full floor pan and inner rockers. Point is take a real hard look at the whole thing before maiing any decisions.
This is a pretty common repair so thier are plent of how to's and Picture posts to help.

BTW I have a full drivers side pan I can sell you its goodmark Willing to sell cheap or trade.

Will get my wire wheel and do some investigating,let you know if i need the fullpan.
