Could anyone post pictures of how vent cable attaches to heater box? Mine was already out of car when I bought it and just installed restored heater box non/ac and not sure how cable is held in place. There is 2 fins with holes not sure if I pinch cable between them and insert small bolt and nut. Just not sure.

Don't have photos, but screen capped from the service manuals, both 71 and 72. They're the same, but the 72 manual shows closeups that the 71 doesn't - view in circle W & Z. So it looks like the left outside vent uses a sort of strap clam, and the other 3 cables are retained between two spring-loaded "flaps", or fins as you called them. Doesn't look like any bolts, except one holding the strap clamp.

Thanks , this really helps a lot!

glad it helped. sometimes the service manual shows just what you need, and other times it's about useless.
