front axle big 7 radius arm bolt removal heat
#5
1/2 inch bolts out.  In the end I had to take it over to a machine shop where the elderly man drilled them out.....he said it was quite a struggle.  Interestingly the bolts did not have a waist cut in them in the middle.  I have some new 1/2 inch BSF bolts and had to cut the thread a little further up.  Next stage will be to see if I have to turn down under the head to get that part sitting in the recess in the top of the radius arm. I may just fill the recess with a washer. Why on earth was that turned head with a little peg used???
There is plenty of room between spring eye and top of head of bolt using the original type BIG 7 spring shackles.  
I await with bated breath to see how easily the shackle bushes go in and how free the pins are......because of course the interior of the bush has a course thread as does the pin so no reaming here.
