Outstanding quality. Took less than an hour to install. Taped the template to the firewall which made drilling the holes a piece of cake. Used a step drill for the large center hole.
Much smaller than I thought it would be. The included template made installation quick and painless.
Yes, you will need the .188 which is P/N# 05-00957.
Yes, the ball splits in half so you can clamp it over the cable.
The A-920 housing is 1/4" O.D.. You can use the .250" or for a firm grip, the .240" unit to secure it.
