The antenna grommet on my 06 XK8 has completely dry rotted. Is there a better source for the antenna grommet than JagBits (seems pricey at over $30)?

 

Looks like my best option would be to buy the entire antenna motor/mast kit from Ebay. It appears to include a selection of grommets and I need a new mast anyway. Not sure if my motor needs replacement or to be taken apart. Either way, might as well put in a new one if the cost is minimal.

 

I would just delete it and look into installing something that is not meant for intergalactic communication.
