Engine/Transmission Spacer for a GT500 1967 Automatic and 4 Speed

[Kent]

Hello I´m just sitting over some of my notes that are now older than 20 years and I wonder if its right that there are 2 different block/transmission spacer plates for a 67 GT500 C3AZ-7007-D for an automatic and C3AZ-7007-B for an 4 speed. Both have the big hole for the camshaft. Is that right? Thanks, Kent
