7EC/FC mods

Finally getting around to finishing an old 7EC that's been sitting in my hangar for years and have some mods I'd like to do to it.

First, I have a set of Citabria toe brakes and hardware and the weld-in hoops to convert it from heel brakes. Since the new EC's have toe brakes (I think), is this an approved mod or did the factory have to do a field approval? It's already got hydraulic brakes.

Second, I'd like to do away with the "diaper bag-style" baggage compartment and extend the floorboards and put a bulkhead in further back like a Citabria so I can carry a bag or two. I guess the same question about the new EC's. Is that an approved mod?

Got a C-90 with a vacuum pump (-16 I think) and would like to use it and do away with the venturies on the side of the boot cowl.

Would like to put a skylight in it.

Anyone know anything about weld-on float fittings?

Airplane's at ENW, serial number 400.

Thanks in advance,

Steve
