I use a Meziere flex plate and Reid bell / trans case




I'm going on 30 years of Powerglide use in 4 different cars (big block and small block) and have never hurt a JW Flexplate. I am almost paranoid about starter installation and spend hours getting them shimmed right. Almost every combo I set up is shimmed differently some with the nose on but many I have cut the nose of the starter off. Shim kits come in VERY handy and are available at Summit.
