IIRC, the best years for AOD's are from '88 and up. The earlier ones had a lubrication problem for the overdrive. They would seize up if used for high speeds or prolonged times. Cop cars use to have a warning label telling not to use OD!
The good news is that they can be convertered to the newer style. Ford use to sell a "rear lube" retrofit kit for these. The 90 trans should be fine. A lot of parts interchange with the electronic version too.
They should bolt up to your 351C, as the C shares the same bolt pattern as 302's and 351W's and these are the only engines besides 6 cyls that used this trans.
