More instructions

In today's day and age it's really easy to print out some instructions and throw them in a box it would also be nice if you could have somebody answer the phone and it has a little bit of knowledge instead of calling me back in two days

Great service

Chrysler tech for years. First gm car picked up with a trashed head and broken timing chain for a commuter car. Used zz performance parts for pretty much everything. Car runs like new for an awesome price.
