/ on Rodney Dickman clutch master cyl.bushing size. (Page 1/1) johnt671 APR 30, 02:56 PM I need to replace my clutch master cylinder and want to use Rodney's. Please save a 69 year old back from having to get under the dash to see what size shaft and bushing I need, The clutch pedal was replaced by me years ago with one from the Fiero Store but I don't know what size the bushing was, large or small. I just looked at a picture of the Fiero Stores pedal and to me it looks like it has a small shaft but I can't be sure. Thanks. fieroguru APR 30, 02:59 PM Only way to know for sure is to check. Use your cell phone to take a video or picture.
