I am beginning to formulate the battle plan for replacing the floor pans and front frame rails on the project car.  It looks like there are a few good options available for purchasing new

pieces.  Other small areas that should be replaced I am pretty confident I can fabricate some repair pieces with 20 gauge sheet metal.  The spare tire compartment is in real poor shape.  I do not have any confidence of fabricating that part.  I have looked at a few trunk sections from some newer vehicles and have come very close with the same dimensions as the original.  Any thoughts on cutting one out of a salvage yard car and dropping it into the 280Z?  The 2 hanger brackets on the bottom of the spare tire compartment could be easily welded on the replacement component.  There are no intentions of this project being a show piece, just a solid fun runner on a budget .  It seems that the depths of the newer car compartments are a bit deeper than the original, but the diameters are nearly identical.  I am sure roaming through our local Pull-A-Part I can locate  something very close.  Any helpful suggestions welcomed.  Thanks again, John-Lugoff, SC.

What year is your car? I have a spare tire well from a 240z. It has a few pinholes but very useable if it will fit your application...

And if Charles's tire well doesn't work out I'm sure there are a few up for grabs from the guys at Hybridz,

Many tire wells are removed for modifications.

I just happen to have a spare tire well from a 77' . Should be the same for a 78'.  It's in fair shape and already out of the car. Let me know if you are interested.

Thanks for the responses.  Been very busy at work this past week and several other projects going on at home and church, so the Z project got put to the back burner.

Did not even check my e-mails or Z-car site.  I will have to check out the map for the GA location and see if it is any where near our daughter.  I never realized how big a state Georgia was until they moved there and purchased a home .  They are about 4-4-1/2 hours away from us.  We will see how things work out.  Shipping such a part would be awkward and costly.  Thanks again, John-Lugoff,SC.

This will give you a good idea of how to get to Greg's place. https://www.google.com/maps/dir/Cohutta,+GA/Lugoff,+SC+29078/@34.3087835,-83.9771355,8z/data=!3m1!4b1!4m13!4m12!1m5!1m1!1s0x886078136ab0abfd:0x607ffea3819d63a8!2m2!1d-84.9527235!2d34.9595209!1m5!1m1!1s0x8855f9301a989ad7:0x9aaecd3c9951c49a!2m2!1d-80.6892486!2d34.2273712

Frankly the road that cuts through Tennessee looks to be the most enjoyable route.  

Greg is good Z people, too. It would be worth the trip for you.
