Colin,
Might be worth contacting Sports and Vintage Motors of Shrewsbury, I believe they supply 5/16" BSF High Tensile Racing Quality Big End Bolts and Nuts for the MG M, D, J, F1, F2, F3 and PA Types - whether they're of the correct length and head type / shape to fit your Speedy / Nippy rods and crankcase I can't say - but no harm in asking.

1935 to 1948 Morris Eight Big End Bolts are M8 x 1.0 mmp but probably too long at 44mm - they have a chamfered all round head with a locating flat, but no pin - torque is 25 lb ft.
