Bucket seat questions

[Omaha68C10]

I scored a pair of low back bucket seats today out of a low mile 74 chevy ambulance at the local U-pull it yard for 25 bucks. They look very similar to what would have come factory on my 68 C10. I am planing on useing a mid 70's Blazer center console with these seats for stock appearing set up. Any ideas on what would work for mounting bases? There was a mid 70's GMC in the yard to with factory high back bucket seats and I was thinking about useing thoses bases.
