Joe, 83-84 Mustang V-8 T-5= NON world Class. 82-87 Camaro V-8= NON world Class. 85 began World Class T-5 in Mustang V-8 88 began World Class T-5 in Camaro V-8 The clusters and 1-2&3rd gears from Camaro Non world class should be the same as the AMC in interchange, The only way to find out for sure is to get my hands on one! I know Camaro uses the wrong input, but the rebuild kits are the same for most all Non World Class trans, I've checked the parts books. With A 84-85 Mustang V-8 Trans I can even use the input shaft if needed, different pilot bearing I think. My American Runs a 91 Wrangler EFI system on a 95 4.0L engine. i'm not concerend about the non world class status. I believe that if you do a quick web search you will see that indeed the torque rating of World Class transmissions remained at 265 till 1990.
