Hello All. I have an 88 GMC Rally van with a stock interior. My front bucket seats are in great shape and I want to keep them but want to make the passenger a swivel. I have looked at swivel plates and cannot find one for the G-series. I can probably use one from an Astro van and mount it to my stock base but some fabrication will be needed because the swivel bases raise the seat an inch or two and the mounts are slightly different. Another option is to find a junkyard conversion van but those seats use different mounts and are usually trashed. I prefer not to use a floor mounted universal swivel because I like having the storage under the stock Chevy seat base and installing one of those creates carpet "issues".

What are others doing in this situation? Any ideas or suggestions are greatly appreciated. Thanks.

My G20 has 4 swivel seats, but it's a conversion van! You could try one of these universal units if the junkyard doesn't have what you need. http://www.discountvantruck.com/rvvanseatbases/rvvanUniversalseatbases.htm

Any swivel will work... a adapter plate is needed... Alum plate 1/4x11x14...drill a set of bolt holes for the swivel & a set of holes for the bottom of the seats.

Yes I have seen the link to the universal swivel and that is where I am leaning but at $259 I thought I better inquire before throwing down $. If I go that route I will likely cut down the standard chevy base to eliminate the additional inch or two in height.

Thanks.

I got a set of pedestal swivels out if the yard for $75 & $10 for the plate ....

This is what I got out of the yard & cleaned up ...

To get this for less than $100 for a set of 2 ... the gray is the pedestal & the black is the adapter plate.
