does anyone out there know how hard it is to replace the floor in a 280z and also do the rocker panel . i checked out a 280 and the engine is solid but there is a bit of a rust problem. i talked to my friend who owns a body shop and he said it would be alot of work to stop all the rust

It isn't an easy job if you have no body work experience or the right tools. It's going to be a fairly labor intensive job, cutting and fitting, so if you are going to pay a body shop to do it, it's gonna get expensive.

If the job isn't done right, the whole unibody is going to lose its structural integrity, and the car is not going to be around long...

If you have a set of spot weld cutters, and a mig welder, and have some practice with the welder already, do one at a time and see how it goes.

The floor pans are pretty straightforward, the rockers are a bit tricky as they extend under the front fenders and they also are overlapped by the rear inner fender behind the door jamb.

The floor pans are pretty much a cut out and lay them back in. You'll need to move the brake lines and gas line under the passengers side rail, after that it is just a matter of marking it them out and fitting in the new pans. If you get pans, go for the best that Zedd Findings or MSA offer, as they are the thickest metal and the strongest you can get.

If you are going to pay a shop to do them, the parts are going to be about 1/3 the total cost as there will be quite a bit of labor to do the job right..
