I bolted down the 2 front seats and they are leaning towards the door. Is this correct, or do I have to put shims to make them straight? Thanks Ralph

 

I think they should

 

My Seats in my 69 Mach 1 sean to lean way towards the center console when the seatback is pushed forward. They always look a little crooked but seem lined up.

 

If the seat slides back and forth, and is comfortable to you at that angle, then stay put. But if it really bugs you, you can always drill new holes and change the angle. It would make it difficult to get to the bolts from underneath though.
