[TR] 3 point belts in a TR4A

I bought the inertia reel belts from Moss and mounted them using the stock 
TR6 mounts.  The inertia reel mounts on the wheel well just above the parcel 
shelf and there is a belt guide that mounts higher up directly above the 
reel.  The feeds the belt over the shoulder.  The other end of the loop bolts 
to a weld nut just below and behind the lower rear corner of the door 
opening.  The other part of the belt set bolts to a weld nut in the driveshaft 

I do believe the TR4 has different seatbelt provisions but I am not 
familiar with the TR4A but if you don't have the weld nuts you can drill holes and 
use nuts and oversized washers to prevent pull-through which is what I did 
for the guide loop on my TR6 since the 71 didn't come equipped with inertia 
reel belts, just the fixed length three point harness.

If you can, study the mountings on a TR6 and try to approximate as closely 
as you can.  I'm sure the factory spent quite a bit of time optimizing the 
seatbelt mountings so it would be wise to ride their coattails.
