Thorp Air Command - T18.net

I pulled one of the outer wing panels off the airplane the other day and found out the wing bolts are not as called out in the drawing. The drawing calls for AN6-14A (3/8" diameter) at the main spar fitting. The two bolts I removed appear to be AN177-13 (7/16" diameter). The existing bolts are snug through the holes but can be worked in by hand. At a glance, sourcing the correct length AN177 is going to be a challenge but I have more internet to search. If I order AN7 bolts, what are the odds they will fit proper?

Thanks Cubes. Unfortunately they don't show what I need on the web page. I finally found three AN177-14A bolts at Preferred Airparts. Only $25 each! I found a couple of AN7 examples to check fit with. They are a loose fit so it looks like I am stuck unless I want to replace the fittings <NOT!>.

Have you tried https://www.gen-aircraft-hardware.com They carry just about everything except the $5,000 toilet seats !

yep, along with D&D, Skybolt, KRN, Spruce, Spencer, Skygeek, Chief, Aero, Univair, Wag and a few others. Ordered the ones Preferred had but they didn't have the AN365-720 nuts to go with the bolts so those are coming from Spruce (along with some 2 and 3 conductor shielded 18 gauge wire I need for work).
