Identifying early/late model gear legs

[6643]

I don't see why not. There's nothing else serial number specific about the airframes with and without the swept gear, and, the straight legged planes are eligible for the extenders, which are pretty much the same thing. I even heard of a plane that had both. (Not that I'm suggesting that was a good idea.) In fact, swept gear is better than straight gear with extenders (but straight gear without extenders is better still.)

I have removed four sets of extenders, so far. They handle better.

So many aircraft have parts from earlier/later s/n aircraft that it seems to have become standard to mix and match. The forward swept gear "should" have gear box angle brackets in the four corners (fore and aft, both sides along the lower fuselage curve). The brackets are steel and need to be riveted in. "Good luck" locating any.

Yes, they will "bolt right up", if that answers part of your question.

I forgot about that. Victor is correct; if you install the swept gear you should have those doublers. The swept gear load the gearboxes with a twisting moment whereas the straight gear load it parallel to the bulkheads. (Extenders do the same thing, to a lesser extent; a lot of the twisting with extenders is transferred to the gear legs themselves.)
