Hi gang-

Came across this 73 yesterday and just had a look at it. It's pretty nice looking on the outside, repainted over lime green. I've attached some picts of the underside. Specifically the twin I-Beams that have some rust. I guess my question is for the right price say $1500 or less is this worth looking at? The rust worries me and part of me says just turn and walk away as these are the main structural areas with damage. Any feedback would be great.

I'd think 1500 is fine, depending on how good/bad the floors & rails are. Nothing like "hands-on" vs a picture. Maybe you can try an awl or screwdriver & see if the rust is only on the channels beneath the floor pans, or all over. If it is only the channels, Charlie sells those separately at www.datsunzparts.com Quite a bit less $ than floors complete.

Good luck- looks decent in the pics! JA

ps- did you check the battery tray/ spare tire well also?

I have not checked the battery tray area or the spare tire well. The bottom pict shows a hole on the slant of the frame that I can stick my finger into about a half inch or so and seemed as though some metal was peeling away. I didn't go any further until I got a comfortable feel about these rails. The rust does appear at the rear of the rails and there's another spot I forgot about above the rails in the rear part of the front wheel well that is about the size of a shoe, a clean hole on both sides. I have no Idea how easy/hard that would be to replace. I did pull up the carpet and it seemed solid and from underneath there wasn't much for 30 years.

If the rust hasn't spread to the floor pans themselves and is only in the rails it you are looking at a relatively easy fix and not too costly. The hole in the front could be patched easily enough. Check under the battery, check the rocker panels with a magnet for signs of bondo, check the inner and outer rear fender lips for rust or repair and under the hatch above the taillight panel. Looks like it might be a good buy as long as the rust is confined to areas you have shown. Also check the front frame rails around the swaybar mount and look carefully at the inner front fenders around the strut tower bottoms and above the lower control arm from underneath.

If you don't find too much more rust hiding somewhere it looks pretty good in the pic. Good luck.

Thanks for the feedback. We'll have to see what happens.
