They SHOULD all be the same length..............but you never know on a 50 year old car what is/was installed in the past.
The two bolts that thread into blind holes are the critical ones that require checking.........the other two don't really matter as long as they go thru all the rear cover threads.
Reproduction springs and reproduction spring liners are a different thickness than originals, so any changes/replacements to them will also affect the required/needed bolt length. Do not just assume that all is well.
