Shifter boot?

If they're splitting where the stick comes thru the hole
then they're sized wrong or
they're junk
The boot should be shiney
The one in the picture is sorta flat and coarse looking.I have seen this kind of rubber before, and in most cases, that kind of rubber has no inherent strength, kindof like an old rubber band that's been in the sun too long.
The shiney ones, like the factory had, can last for;lessee how old is mine? hmm; I think it's a 1969 model, so 50 years-ish
