dipstick insulation in hemi

Any places have just the insulation without buying the tube and all for a hemi?

I bought just the insulation for my dipstick along with a bunch of other hemi specific stuff from a guy quite a while ago.

His name is Phil Newcomb. His buisness used to be Phil Newcomb Hemispherical Products. I don't know if he is still in buisness or in the hobby but Google shows some possible phone numbers you could try.

I think Year One sells that separate.

Thank you. I am about 15 minutes from Jegs warehouse and picked up some generic stuff. Not quite the same but should solve my problems
