Replacement spring bar source for USA JB Champion

[bncapass1]

Does anyone know a replacement spring bar source for the vintage 1960's - 70's Rolex oval USA JB Champion jubilee? This is the tiny removable link spring bars and as you can see are quite worn although functional. My recollection for how to measure is a bit rusty but I always though it was compressed however this way I'm getting 7.71 mm which no such bars exist and 8mm would be to big and 7mm to small. Spring bars are probably one of the very few areas that I will use quality swiss made replacements instead of OEM Rolex.

I measured an oval link without the pin and the space is about 7.5mm. Is that about the same for you?
There are some 7.5mm available at Ofrei..

Yes about 7.5mm is what I'm getting also. I'll check those out. Thanks.
