I just finished installing the rear half of my floor pans. Is there a trick to getting the seat hinge mount located in exactly the right location?

The tilt mechanism seems to be the critical factor on this. if the teeth are too tight you get no adjustment. If the teeth are not seated enough, maybe loose some support or even have a slip out issue.

here are some measurements from a parts car. you could also install the Adj. tooth and mock it all up with the seat rails.

this measurement was taken from the rear firewall

i would think if you get the comb tacked in - you could use a seat rail as a template for the hinges.

Thanks for the replies, I will check the measurements. I am using new aftermarket hinge supports, so I will check for accuracy since the size of the support may be different.

I have been mocking it up with the support bolted to the seat frame
