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.
