I installed by Red Prothane upper motor mount insert = 18mm socket. Slipped right in with not problems. Before I take off my front wheel and spash guard to install the lower I see that the socket needed for the lower is larger. I don't have one that big and need to go out and purchase one prior to the install. I am guessing 22mm? Does anyone know the socket needed for the lower stock motor mount bolt?
Thanks

They have the service manual up here online for download.

Edit: not sure if the size in mm is in there, if you have dial up don't bother downloading it, it's huge.

 

I would have to guess 21mm,


Sorry, it's to damn hot here to go and lay under the car to check!!
