Astro van or Safari with Sienna seats

[6door74]

Does anyone have sienna seats in an Astro Van or GMC Safari? I have a 04 Safari and a 06 E-350. Debating which van to put some Sienna seats in. I don't believe if I've ever seen anyone put them in one of these GM vans, and I don't believe there's any product to make it easy like the weldtec base for the Econoline. Post pics if you've done it.

Thanks
