I need to replace the floor pans of my '66. I've seen two different ones though and am wondering which might be the rigth choice. There is the one whole big complete floorpan and then the two sides RH and LF full length floorpans. The difference in price is big: the two sides are about $60 a piece or $120 for the set. The full floor pan is $450. Which would be better and why?

 

i would think replacing the whole floor would be the best, then you dont have to do as much cutting out but iono, im replacing my whole floor when i can.

 

If the whole floor isn't rusted, I thought people just patched up what they needed. Like, if there is a small section of rust on the driver side near the pedals, why replace the ENTIRE floor of the cabin area? If most of the floor is gone, then yeah, you'll wanna replace it. It's more of a pain to do the whole floor from what I understand. Gotta get it all lined up and perfect. (keep in mind, this is just what I've researched, I have yet to actually peform any work like this on my car)

 

Its a big decision to go with a full floor pan. I would only consider it if the whole floor of your car is rotted out including the tranny tunnel. The tranny tunnel is included in the full pan, it is thicker metal than the floors also. Fitting a full floor is very difficult unless you are an expert welder and body expert. With removing the full pan you are taking out the tranny tunnel which is a major support structure of a unibody car. If your car is not properly supported it can sag and flex causing the floor not to fit and your car to no longer be straight. There are a few posts on here in the past of documenting a full floor and they did it only because everything was gone, try a search for them. So unless everything is completely rotted on the bottom I would stay away from the full pan and just get the two sides. With installing a side you are not hurting the car structurally so it will remain straight.

 

Thanks for all that info. The whole floors are pretty well gone but I don't know about the area of the tranny tunnel. I am not an expert, but will be doing this in my autobody repair class so I should be able to get it right. With the cost though I'll just get the sides if the tunnel area is ok. I didn't realize it was harder to do the whole floorpan.

 

I didn't realize the full floor was harder either. Thanks for the information Remicks and thanks for asking the question in the first place Waldo
