hey, i've got a 66 coupe. im going to be welding in new seat platforms and am wondering if anyone knows of a book or manual with the dimensions i'll need. or if anyone just knows the dimensions from experience. any help is appreciated. thanks!

 

Typically I'd do one at a time, using the other as a reference. Are yours missing now?

 

yeah i had the floor replaced from firewall to rear transition pan. the seat platforms i have is a one piece for the drivers and passenger sides.
