Well in 1960 was the first year they introduced the patroller with long range tanks.

So your neighbors plane was most likely produced late 1959 or is a 1960 or someone put LRT wings on it.??

Since it is a stock cessna part putting on the wings needs a IA that is comfortable with the installation and will document it in a 337.

Chris at Del Air is not selling the STC since his welder died and yes the parts are expensive and installation is not cheap..

Even with all the parts for a stock set of tanks it will cost and it will cost less than the Del-Air but it still is a good amount of work.

If you can do sheet metal work, Rivet, derivet have the tools and someone that you can work and you do a lot of the work,
it will be easily manageable..

To just farm it out yes it will cost $$$.
