Getting my set of BMW seats with belts soon...

I have them bolted in temporarily, but it’s clear the base of the seats are taller, I’m thinking about using dropped floor pans. It’s unclear if the seats are going to deman being hooked up to an ecu, I’ve read conflicting reports on that. Not going to know for at least 8 months.

Could you take pictures as you do your install and post them please? I have to do full floors on a 64 Valiant and I need seats as well - there are none at the moment. I've considered going down the same road you are, any help and info would be appreciated.
