Kevin, The turnplate tanks are made of steel( magnetic ) the replacement tanks for these were made of stainless steel and soldered together. A magnet would not stick to the stainless ether. These tanks were about 9 gal. and can be identified by the notch in the outboard rear bottom for the landing gear on ser. 813 and lower. In the mid ser. numbers they made 8 gal. tanks, they are alum. and can be identified by the ends. they have a indented end with a row of rivets holding the end on in a lip fashion, there are no bludges in the ends they are flat. These tanks had a couple different ways of being plumbed and there were some service bulitins on this I think. The later ser. numbers had 9 gal tanks that can be identified by the bludges in the ends and back, this is how they got the exra fuel in. Ane there was running changes on the plumbing on these too. So as you see there is alot of changes. Sorry I cann't help more. Good luck. Mark
