1968 Carburetor

[otis71]

What model carburetor is correct on a 1968 FLH? I’m thinking HD1C but not positive.

Not sure this helps but my original 69 FLH has an Tillotson HD2D on it. My understanding is that the HD1’s were on sportsters, HD2’s were on big twins. I believe the last character of the model number identifies the revision level.
