Empenage Mounting issue
So I have started on an 8 project that is quite a ways along. When I went to attach the horizontal stab to the fuse today I noticed an issue with the holes that have been previously drilled. As you can see by the pictures, when the 4 holes drilled in the front spar have bolts in them that leaves about a 3/16" gap between the rear spar and the tabs that it attaches to. Am I missing something? Doesn't seem like a likely place to mis drill. Thanks
Guess I don't know how to post the pictures.

Angle
There should be a piece of angle under the rear spar about 3" long between the two longerons. If it were missing, it would leave about 3/16" gap.

This one doesn't have any angle on the rear spar but there is angle of the front spar. The rear attaches to two vertical 1/4" straps the come up from below

I can?t see your pictures but, if I remember correctly you use a 3/16? spacer on the rear spar to level the HS before you drill the holes. It doesn?t lay flat on the fuselage.

Can someone help me post a picture. I have searched all over for instructions. This would help my cause.
I don't have any reason to believe the incidence of the horizontal isn't correct. The puzzling thing is the forward/aft location.

There's a lot of options, so here's the one I think is easiest:
go to imgur.com, click on top left "new post". Drag and drop your picture to it. The result will be a link, like imgur.com/p/aioasjdfiojaso - just post that link in here.
You can get fancier by embedding the pictures, or posting clickable links, but to get going that is the quickest.

Thank you Ctennis. as you can see in the pictures, when the bolts are installed to hold down the front spar, this leaves a gap for the rear spar. Leaves me scratching my head. Its always challenging picking up where someone else left off.

Joel, it is hard to tell in the picture if the plane of the aft spar is behind the slot for the ears. There was one here in the past and the ears were not vertical. They should be.
First take a rule and slide down the spar to see where it intersects on the deck, then you might check to see if the ears are perpendicular to the deck. HS might have to be off.
One like this was posted here recently ( last month or so?) but I can not find it.

I will walk down the hangar and check that. I do believe it is aft of the slots, The ears did appear to be vertical and not bent. I will double check however
