I've got my 87 GN ready for cage and chassis work. Originally I was planning on going 25.5 but am thinking about 25.3. Curious if anyone's updated to a 25.3 from 25.5? I'd like to see some pics in a turbo Buick. Also not too familiar with how much more work a 25.3 cage is so any input is welcome. Thanks.
