Seat question

[volaredon]

I am working on my 85 D150.
I got a too good to pass on deal on a pair of matching ramcharger buckets.
Problem is they didn't come with the riser bases. Still a good deal.
Are these the same between truck and van?

The seat, yes. The riser, no.
There is a difference between 70's and 80's (not exactly what year the change was) seat bolt pattern.
I wanted to put a nice set of cloth 85 Ramcharger seats in my 77 van, but nope still rocking the high back vinyl.
