No, the team bikes were equipped with full C-Record, so I'm pretty sure they would have used the non-indexing C-Record shifters (Synchro came out the following year, 1987). I wasn't going for complete parts accuracy with this build since I bought it as a frame only and had a lot of these parts on the bike back in the 80s. The Campagnolo parts you see are mostly Chorus (except for a C-Record BB and crankset), along with a smattering of Mavic parts (headset & hubs; Mavic wasn't a La Vie Claire sponsor, bit they are French at least). But even if I had a full C-Record group for it, I'd probably use Simplex retrofriction shifters anyway since they work so well.

Thanks, GB. I know you know your way around a paint gun and don't throw out compliments easily, so that means a lot coming from you.
