I have a couple b-body rally dash questions. If a car didn’t come with a clock, was the reset knob hole (in the lens) plugged, or was it open whether it had a clock or not? Also, are the small push pin clips that hold the lens assembly on available anywhere? Thanks in advance

'68 & '69 Plymouth Bs weren't "rally clusters" like the '70 (and SuperBee/Charger) clusters.
My '68 RR (with tach) and my '69 RR (no tach or clock) have a raised "dot" where the clock-winder would be.
May be plugs, but they'd be the tightest & smallest plugs known to man. I didn't pick at them.
Been decades since I had one with a clock, so I can't help there.
I can't recall what my Chargers had & haven't had a '70 RR/GTX...yet...

1968-69 Rallye cluster was Dodge only, standard in Super Bee & Charger and optional in Coronet RT.
All 68-69 Rallye clusters had clock as standard and tach optional, so all had the adjustment stem. In 1970 they were available on Plymouth and Dodge models. There was a clock delete plate as standard. Clock or tach were optional. I have never seen a 68-70 B body lens without the hole for adjustment stem. The clips are available in aftermarket, check Ebay.

the non clock dash had a small clear plastic plug. I had one around here somewhere.

Thanks for the replies. Does anyone have a link to where the lens push pins are available? I’m having trouble finding them.
