Utility Bucket help

[NW_Ryker]

Sorry guys, I feel like I'm posting a lot in this section. This is my first time building a truck from this era and need some help. The PO put some aftermarket seats in my 71 blazer that use a 2x4 to attach the seat to the slider/floor. A user on here is selling a pair of utility buckets near me from a 70 I believe. It's just the foam and frame. Will these work with a 71 seat covering? I'm trying to go the original route and the covers I want to use have the scroll inserts. Thanks!
