I did some different style bucket seats in my 68 RR
wanted to get away from the bench seat it came with
I also wanted something better than stock style buckets too...
I went with a Pro-Car Scat Elite 1100 in black,
Nice light seats, nice bolsters, nice seat back adj., nice material,
nice adj. head rests, a bit "lower profile", sits low,
looks a tad bit more era correct, for my project style,
not that that matters
IIRC they have leather too, may have to check it might be foe leatheret
they had premade seat brackets & slides too,
it was 7-8 year ago IIRC
I had to drill the 2 holes on each side by the tunnel,
other that that a bolt in, easy peasy stuff...
$750+ for both a dr. left & pass. right bucket seat
both dr. left & pass. right seat mounting brackets,
from either Jegs or Summit, delivered for free
click on the photos it has the part #'s
I liked them they are comfortable & lower than many aftermarket seat
I have a tall upper body torso, I wanted more headroom & comfort
in a performance seat that looked nice & held me in place,
they did all the above, I think they are a little more $$$ now...
I was surprised how nice & comfy they are...
You could easily do a harness with them too,
I have the lower sfi style belts & a factory shoulder strap,
when I'm done with other stuff I will add a roll-bar &
add the uppers of the harness too...
Just Another Option
IMO, I found the seats with the molded hi-backs
are restricting my view over the shoulder & out the back...
No big deal really, that was the only negative,
partially why I choose the seats I have today...
Partially more fit the era of my build too, like a early 70's day 2 car...
