'70 Duster Vinyl Top Question

Thanks for the input sleeper. To be honest, the top was one of the "negatives" when I considered buying the car. The other was the column shift. To change either would be entirely illegal for this restoration of a car that still had the AM radio in the dash. I've since changed my mind on the top and I now think I'm gonna really like it. You got any input on the 36/41 issue? Sounds like guys are saying it should be 36. Curious to see what the vendor says Monday.
