Got a guy who is in drafting in anything engineering (usually does high rise windows!!!!) so will get him to have a look when here next - Also Nigel should be here in the next few weeks. My aircraft welder Rowan must have forgotten to call in when driving past -he could look and give a round figure price.
Another alternative I have always thought of is instead of 250-4 tire is change to the bigger tyre (will look up size) as used on some C185s - I saw this used on every Pawnee in Sweden but never seen it on a Pawnee in AUS. Possibly a simpler mod but it may effect shimmy- Yes it would be a bit heavier but not much and from memory most Dimonas would benefit from bit more tail weight Guess it would need EO also but I always know bigger bag tyres smooth up ride (going from 800-6 in pawnee to 850-6 is leap forward as was going from 500-5 to 380-150 in 2 wheel falke.
