Modifying Skymaster landing gear

[cessnadriver]

I'm seriously considering buying a C337A (PROJECT). Here's my question. I'd like
to convert a C337A from RG to permanently fixed gear. Does anyone know A
DAR/DER that I can give me information about this pursuit? I'd like to know the
following. 1) Is this change over possible? 2) Will I have to do an STC, or can
I just get it approved and possibly sell the information (documentation) to some
one that wants to do the same conversion? 3) If do-able, will I be able to
remove all hydraulics, lines pumps, cylinders and increase the USEFUL weight?
I'm an A&P and will do most of the work. Any and all information/advise will be
deeply appreciated!
