Make sure you undo the hub nuts if you're going to refurb the driveshafts/uprights while they're still fitted on the car; it's a lot easier! The front nuts are an unusual size (29mm), the rear nuts can be 29 or 32mm depending on the car.
 
The whole rear section can be a PITA; the driveshafts can get properly stuck in the uprights and the lower wishbone to upright bolt is exposed, so removal a lot of the time can be problematic.
 
You'll most likely have an issue with the steering rack fouling the front lower wishbones at full lock and droop; there's lots of examples over in the States where the Miata has been a popular donor car for a lot longer than over here. There are several ways to fix it, which are covered on the forum.
 
You'll need a custom tank anyway, you can use the MX-5 sender and pump, you might need to modify it. Someone might even have a MX-5 tank for sale   
Where in the world are you?

 PorkChop,
How did you get the bolt out in the end? My donor has only done 65k, so thought it would be easy, but it's a real bitch. It's basically swimming in WD40, trying to turn it to loosen the damn thing (limited success) and I've even tried a sledge, but that's just damaging the end of the bolt.
Any suggestions welcome.
