[TR] TR3A Seat Belt Hole Location Question

What a coincidence! The seat belts I ordered for my TR3a resto arrived
Friday eve. I looked around a bit and didn't really see a good place to
mount them. When I read your post today, I looked at the car and the
location you reference seems very logical. The only problem is that I don't
think the belts are long enough to surround my lard when attached there. I
did get the kind that attach via eye bolt which seems to be what was
preferred by the boy racers of the period. The belt on the clip side is 20"
and on the buckle side is 36" when fully extended.

Anyone use this location and know for sure what fits?

As to the offset, they may done this to reduce metal fatigue when the bolt
holes are under stress. Yeah, I know, that sounds like BS ... and it
probably is!

Greetings Listers,

Before I drill holes in the( heal board) for seat belts in my 60,000 S/ 
N car, I wonder if anyone can offer an explanation why the inboard and  
the outboard holes should be at different heights from the floor. The  
Standard-Triumph Motor Company, Inc. Northeastern zone Service  
Memorandum #2-62, January 9, 1962. shows out board holes 2 5/16" from  
the floor and the inboard holes 1 7/16" from the floor. Also the memo  
shows the holes should be 2 1/8" from the driveshaft tunnel and 1 1/2  
" from the wheel arch side.
Why not holes on the same plane and evenly spaced from both sides.  
I've studied this memo and feel fairly confident I'm reading it  
correctly but I don't get the logic here.
