Hi Bruce,

The original big end diameter was 47.990 – 48.000mm ( ref – http://www.ctaservice.se/tek/tekinfo.htm). Shells are available in steps of +0.25mm from all suppliers.
I think you may need to go +0.75 to ensure #1 cleans up. Your grinder will know best.
All the suppliers seem only to list con rods in sets of 4. Individual engine builders like John Gillard may have a single one knocking around (new or second hand). Maybe the major suppliers too – even though they don’t list them they have already broken a set. Worth calling Chris T at TOC Spares too, I believe he has more than is on the spares list.
Leo Quinn is advertising a garage clearout of enginer spares in the back of F-P – leoquinn1950@gmail.com.

It’s a very open question as to what else needs to be replaced. There’s a thrust washer at the timing gear end of the crankshaft which needs shimming to get the correct end float. So you may need to get some more of them. They come in 0.1, 0.25 and 0.5 mm thicknesses, 461125, A, B, C (Franssen and CAS have them).
of course you’ll need the sump gasket set and graphite cord crankshaft oil seal. Chris T knows what’s needed and what’s in which kit.
