I am planning on replacing the Complete assembly I've been quoted on both the OEM unit as well as an aftermarket unit.

I am very experienced with older Raymonds (74 - 84) and mostly with Cars of any age.

If I am to replace the entire assembly will there be any specific tools that I will require? Is this a bolt in unit? I have access to an abundance of professional automotive tools, etc.

Any help is relished at this time. Thanks.
