Lookin good Al!
Where did you get the caulk. Every harware store used to have that... Looked at Home Depot last week and couldn't find it. I am going to put back panels in the duster soon. Got some plastic at work that was on its way to the dumpster, lol. The plastic on mine was in little bits. Also, what tape are you talking about? I think they just used the caulk on my '75.
