Drive shaft loop color??

[Bernhard]

Thanks Dave and Paul for the help. I would like to post pictures but I lack the skill at this time.
The loop that I have is a generic brand like Mr Gasket that was popular in the late 70's./early 80's The loop has four holes like the Lakewood loop. Whats kinda funny is I made a copy of the generic loop back in high school from one that my brother had.My friend still runs the one I made in shop class back in 1980 and is what got me thinking about day two drive shaft loops. I was just over at his house and he has his car apart for a frame off and parts to the loop were on the work bench.
Of the two brand name hoops is one heavier built than the other?
