Rear seat belt bolts 71 vert

[Xghobo]

Having issues with rear seat belt bolts for 71 convertible, I have and installed C11 bolts but for the outer belt they seem too long. They are 1 1/4 long threads and shoulder with the shoulder being 3/8. I cannot tighten all the way due to hitting wheel well so I have 1 or 2 threads plus the 3/8 shoulder sticking out both sides. Now will this interfere with the rear seat? Also it looks like I should be using C13 bolts which I do not have but are they shorter? Anyone have the measurements of a C13?

X @Xghobo  The seat belt bolts are different for 1970 vs 1971.  Here's my list of the seat belt bolt sizes and locations might help.

1970
Qty 2 C-01 = (full thread) Front Retractors
Qty 6 C-11 = Shoulder / Back Seat
Qty 2 C-12 = Front Buckles

1971
Qty 2 C-10 = Front Retractors
Qty 2 C-11 = Front Shoulder
Qty 2 C-12 = Front Buckles
Qty 4 C-13 = Back Seat
