Not likely but: make sure your main gear leg mounts are part number
WD-721 (RV7A) and not part number WD-921 (RV9A). The parts have been
mixed up at Van's in the past, especially early on in shipments.
The RV7A gear mounts have three large holes and one much smaller hole in
the top, while the RV9A mounts have just 3 large holes in the top. They
are very close in specifications and look interchangeable; but, are not.

Yes the bolt head is 1/4" from the main spar. I tried tapping it in
further with a rivet gun, but no luck. I am wondering while the
threaded part of the bolt goes through the hole in the steel plate of
the gear attachment, can the shank, which is a little greater in
diameter than the threads, be to big to go through the hole? As I said,
the bolt on the other wing worked OK. I'll keep trying.

Are you saying it's the bolt head that's 1/4" from the main spar? I
believe I got a flat screwdriver or some other object -- maybe a bucking
bar, I forget -- and tapped it with a rubber mallet or a rivet gun set
on very low pressure.

Subject: RV7-List: Installing wing bolts on RV-7A
I am having a problem trying to seat the lower left 7/16 wing attach
bolt on the left wing. I had no problem with the similar bolt on the
right wing. This is the bolt that's behind the landing gear structure,
the most difficult to get a wrench on its nut.
I oiled the bolt, and can wrench it to within about 1/4 inch from the
main spar, but can not wrench any more. I tried wiggling the wing and
loosened the 1/4 bolt next to it, it's the only other bolt installed.
But, no luck. it just won't turn. I hate to put a long pipe on the the
1/2 drive ratchet the I am using for fear of distorting the bolt head.
Any ideas would be appreciated.
