Stumped...

I understood there were 2 types....the first ended in 75, the second finished the car off.
I see Mikey/Mark of 914rubber sells 2 versions...the first is 72-74...then 75-76.

Are there 3?
If there are, damned if I don't need to hunt down the first version.....

Thanks

This is basket weave (early style)



This is square weave (late style for 75-76)
