Bill,
Here’s a picture of my Ranchero

I am looking at installing a 5 speed in my 58 Ranchero with a warmed up 352 and a cruiso that is worn out .I have some of the parts but I don’t remember what the bell housing is from and also do I need to install a block plate between the bell housing and block like on a automatic?
The bell housing casting number is C60A-6384-D and it also has a big Z cast by the numbers . If I remember this is a passenger car bell ?
Thanks
