'67 Camaro convertible top: 32 or 38 ounce?

[Tim Greer]

Hi,

I'm looking for a top for a 1967 RS convertible Camaro, and I'm probably wanting the glass window instead of the correct plastic window (I don't like the idea of the plastic window degrading and being difficult to see out of years from now), and I'm seeing a 32 ounce and 38 ounce option. What's the difference besides the weight? This is a power top, so I'd imagine the 38 ounce could add extra strain? What are the advantages/disadvantages, if any? Would it matter?

Also, would the glass rear window potentially create a problem with an electric/power top and should I go for the plastic window for any reason (besides being originally correct, which I don't care about?) Finally, is there any brand or manufacturer where some are better quality than others for tops, or are they all pretty much the same? I'm just looking for a black top, but nothing that _has_ to be original for show purposes or anything. Thanks for any insight you can provide.
