oh boy, so been looking for hours now, found adapter plates being custom made (NLA now?) I keep having issues with my transmissions; my second FS5W71B (I think, out of an '81, the original was burnt out from the owner prior to myself). had the used 81 unit in the car for about a year now, and second has been gradually making more and more noise . looking for a supposed sticky on this swap, but any information would be helpful. FS5R30A (Z31T/Z32na) tranny swap to L28E '79
Thanks
