my power split bench seat with fold down middle arm is dead due to switch plug in door being fried melted and the switch missing

i have no way to find switch and plug for this so i was wantngi to know if all 80-90 years caprices and/or all b bodies shared same bench seat mounting brackets and/or floorpan shape/design/mounting hole locations ?

also are there any gm car bucket front seats that will bolt into an 88 caprice ? like monza or nova or something buckets, not high backs though

anyone here put any GM factory low back buckets in their caprice from another year make model GM car ?

gimme details if you could, what fits what doesnt and what you did to make them work ?

thanks i appreciate :D
