The rods that I have measure 21.76mm so the should be perfect in an SC based engine. The small end is bushed and honed for a 22mm piston pin and the overall length is the same for both models. The rods that I have weigh in at:
1 702 grams
2 702 grams
3 702 grams
4 703 grams
5 704 grams
6 702 grams
The factory delta for a rod set is a max of 9 grams so these should be fine. All they need now is a new set of rod bolts and nuts.

Strangely enough, I've just weighed my 965 rods (930 part numbered, though) for my rebuild...without bolts, nuts and shells, they're a fair bit lighter than the ones you describe above --->
Spencers rod weights
Small ends now bushed for a 22mm pin, and have been checked for centre-centre dimensions and ovality (although I don't believe any correction work was needed)
....not being confrontational, just a casual observation....it's been tonights activity plugging the numbers into Excel to get the combinations to balance.
