71 bucket seat converstion question

[Midnight_Rider]

Hey all, I just finished installing the driver's side floor pan and plan on converting from bench seat to buckets.

I got the reinforcement plates for buckets marked off today on the new pan so I know where to take it down to metal to weld them in, but the (original?) passenger side didn't have the same holes to mount the seat that the new one did. I did see some dimples on the passenger side that looked like they may be locaters to drill for buckets, but they don't seem to mirror the spacing from the tunnel on the driver's side.

Can anyone tell me if the driver and passenger bucket mounts are asymmetrical? Or have measurements or a template? I do not have a set of buckets on hand to check for myself.

This is for a 71 Road Runner.

Mirror the spacing from the tunnel? The drive train, hence the tunnel, is not on the body centerline, off-set to the passenger side by an inch or two. Check your seat spacing from the distance to the sills, dimples are there for that purpose.

Agree if you mean side to side.

The distance between the tracks should be the same, but the pass side is closer to the tunnel (I guess technically the tunnel is closer to the pass side).

Now if you're talking about front to back, that should be the same.

Wow. Cannot believe I forgot that.

This is my first Mopar build, but still... I knew that. Dimples make it simple.

Thanks guys.

Here's some dimensions to go by to make sure the holes will be in the right place.

Keep in mind that dimples are more like guidelines to quote Captain Barbosa. They represent where the factory wanted the seats, but might not be where you want them. I'm 6'6", and need extra legroom, so I installed me seats about two inches further back than where the factory had them. I just drilled new holes and made some reinforcement strips from steel bar stock from Home Depot. I also raised the rear of the seat two inches by cutting off the original mounting studs and welding on new bolts, then put a 2" spacer over them to hold them up. This gives me a much better seating position for driving.

Awesome! Thank you. That not only helps me, but anybody else in the same boat that turns this thread up with a search.

Yeah good point, I can see where you might need to make some adjustments. Me being under 6', I figure the stock location is fine. I do plan to use later model seats to gain a little more side support and adjustability (recline), but I'd rather modifiy the seat in this case. Seen lots of vintage Mustang guys around your size on forums who were cutting the seat pans down, and I still don't know how they fit in those things.

I forgot to add that I did measure mine this morning before work, and they were spot on with your dimensions, including the dimples.
