Good thought John.
The Reliant crank is usually fitted together with (slightly modified) Reliant rods.
It has been done with A7 rods though, notably the 10,000 mile record car (I think for the record attempt it ran with custom made rods from Paul Bonewell but it later reverted to modified A7 rods i.e. with some added offset).
The presence of an Austin part number (as above) I guess is the quickest way for the unfamiliar to confirm.
