I've always found this question interesting as well, and hard to pin down.

If I'm reading the Chevy data correctly, it appears to indicate 40-45 lbs (using the difference between the 300 deluxe and 300 deluxe sport coupe).

I was trying to find Olds data a while back... shipping weights for '68 Hurst/Olds between the holiday (non post) and sport coupe (post) were only listed as a 10 lb difference. The AMA specs show curb weight at 3726 vs 3716, and shipping weight as 3568 vs 3558.

I've seen other numbers that indicate 20-30 lbs difference, with an overall range from 10-50 lb.

If anybody else had better info, it would be interesting to know...
