Fitment question about ProCar seat mounting adapters for 1970 Charger

[Coelacanth]

I've read that others on here have installed ProCar seats with their Mopar adapters and things went nice and smooth, but I'm seeing a lot of reviews saying the fitment isn't even close for a '69 Charger. Mine is a '70 so I assume the mount holes are the same. The adapters are P/N's SCA81342 and SCA81343 for driver and passenger side, respectively. The company website seems to indicate the same part numbers for 1966 - 1977 Chargers, which sounds dodgy as those cars can't all have the same bolt hole spacing.

Anybody have experience with ProCar seats in 2nd-gen B-bodies or a Charger? I have a set of these seats and want to know what I'm up against.

I wasn’t happy with the holes in the new amd floor I put in. I measured off the fire wall set a line on each side to trans tunnel found the center lines made a print and moved the seat to fit the console better and sit centered in the car. If I remember right it was 3/8 out, and similar to the right side. I plug welded the holes and then redrilled the holes. You might have to do something like that. Or make a shim and it to the adapter if it needs to come up. I have shimmed seats in the past if it’s out. If you set the seat rails up in the middle of the adjustment and use center lines you for the spread on the rails you can’t miss. If you have to take away, may as well build your own adapter. Make a print from the original

Well I just put the order in for some seats and those adapters, so I'll update here or on my build thread with how it goes.

I put in the driver’s seat in today, and adapter didn’t need shimming but I will have to drill the holes near the trans hump since this was a bench seat car. I was not impressed with the fitment when bolting the sliders to the seats and then again not happy with how the bottom of the sliders matched with the adapter. Holes were off and had to be strong armed a bit.

The pass side adapter would not lay in a spot that would give the pass seat the same spacing to the hump as the driver's seat. I had to massage the floor to move it and even now its not as close to the hump as the driver's seat, but that could be a plus in a way.
Also the supplied rails on the pass seat just would not line up with the bolt holes and needed a hole in the rail opened up.
Now that both are in I can see a little bit of shimming will be needed as well, on the plus side. Bitching aside now that they are in I really like them and they are really comfortable, may be the best seating in my little fleet.
