Although this thread ran a few days ago, I have been on vacation (still am, 
actually) so I didn't see it.  Hope the following is still of some relevance.

When I discovered that the gear legs in my LNC2 were too long to fit between 
the main and rear spars, I contacted Lancair.  They said they were aware of 
this happening on a few early kits and immediately offered to fix it.  I sent 
them the two gear legs along with some dimensions of exactly how long I 
needed them.  They had their supplier (Snowline ?) rework the legs to my 
specifications and then repaint them for FREE.  I also had them remove the 
lever for the cable actuated inner gear doors at the same time.  My only 
costs in all of this were shipping.  My kit dates from 1989 (SN 476, FB 45, 
IIRC). It was in the mid-nineties that I had the rework done.  Whether they 
are still doing this for free I don't know but it sure wouldn't hurt to ask! 
Although it will take a couple of weeks, it is the cleanest solution for this 
problem, IMHO.

Although the following cautions should be obvious, I will mention them 
anyway.  The critical dimension is between the faces of the trunnion 
shoulders, not the ends of the trunnions.  The ends can be ground off if you 
have to.  You should measure the available distance as accurately as possible 
(not easy since it is an inside measurement) and then specify them a little 
short (e.g., 1/32 to 1/16 inch) and make up the difference with a buildup of 
BIDs under the aft bearing block.  That way you have a little left-right 
adjustment to get the wheel alignment correct and still get a nice tight fit 
between the spherical bearings and the shoulders on the gear legs and thus 
avoid having the gear legs shift fore-and-aft during use.
