Are 99 Astro Van Bucket Seat Risers The Same As 88-94 C/K Trucks?

[cris well]

I found these on Ebay from a 99 Astro and they look just like the ones from the van. Not sure what year the van is but I think they are the same.

They look very similar to the truck risers to me but I'm not sure if the bolt holes are the same width and depth as the trucks are.

I can get a set of nice vinyl cargo-van seats/risers for free and I'm looking at a 93 Chevy truck to buy with a bench in it now that is fairly worn.

I'm pretty sure I'll have to drill the 4 inner holes out anyway but was hoping the 2 outer holes for each seat would be the same.

Thanks

They look about two inches taller to me.

I found some and measured the differences.

The van risers are about 1/2" taller, and they are 2" deeper (front to rear) where they bolt down to the floorboard. 13" in the van, 11" in the truck.

Not sure if the width is also different because the truck had a bench seat, but the risers are the same in the trucks, bench and buckets.
