I'm guessing it would be a bolt in swap. I can't see where Chevrolet would have made two seperate floorplan molds or sets of seat tracks for that, especially when they were each available in '78...in the limited production Pace Cars and standard seats in the more higher production numbers of standard models.

Maybe someone else can speak more authoritatively on the subject, but considering the influence the bean counters have at GM (they would have killed the Corvette altogether if they could have), it seems likely the two seats would share the seat track assemblies. Chevrolet had a tough enough time justifying the money making the change to a fastback rear window in '78 since most efforts were directed towards emission and saftey compliance throughout the industry at that time.

  I have them both. Never noticed a pattern difference, but I'll check and report back tomorrow.aceinthehole4938797.8917592593

They should bolt in with no problem. The floors and the seat tracks are the same. Remember, they put the "79" style seats in the '78 Pace cars.

They are a direct fit.....

But on another note:

However ... the 79 seats do not have an adjustment for the angle on the seatback... SOB.... I run with a largre wrench wedged between the seat back and the bottom seat frame...

Ran into a guy selling a adjuster that could be added to these seats years ago in Carlisle.....

Does anyone know of a source for these anymore....

Just curious...

I've been told that if it's a power seat it won't fit in a non power seat car because GM had to deepen the floor pan to accmonate the power seat motor.Not sure if this is correct.

That's a new one! I'm pretty sure there were not two different floors for the different seats. Too much $$ involved for that to be true. I do believe the seats themselves sit a wee bit higher in the car, tho.
And...then again......I was wrong once..........once.

Ron, it was a few years back, when I were about 14-15. My dad told me to do sumpthin, and I told him "F you". Trust me......THAT was wrong!!! And he made sure I unnerstood HOW wrong!!

I have never seen different floor pans in any of the catalogs.  I don't believe that's the case.

Joel, I have a similar conversation and similar reaction with my Dad at a similar age.   Are we brothers????
