I like my plan Find a nut that fits.
Assuming that no one has f**k around with it befor.

According to the book the original bolts would have been on a 2 /2a 2.25 petrol.
3/8 UNF x 1 3/4 long and 3/8 UNF x 1 1/8 long
 
The threads in the flywheel housing are 3/8 unc, the threads on the other end of the studs are 3/8 unf, and therefore so are the nuts.
