Back to your Post #24 questions....
MP Chevy- NHRA/AHRA Modified Production Class, cubic inch to total vehicle weight stick shift race class
My source for input Shafts- Started parting out B-body GTXs and RT cars in the '70s for my '65 Dodge race effort; used the 4spd and Dana cores, also bought a couple complete slick-shifted boxes from Chrysler when they were available from Direct Connection
Red stripe- count the teeth on all the gears and use the chart that I've seen posted here and there to verify
As for the pics of your gears, looks quite a bit of use and they have already been re-dressed, when mine got that bad I would send them back to Joe to get new blocker rings welded on. They can do that many times. I believe his son now runs Liberty's; always excellent service in my dealings with Joe. You may or may not know, but it's absolute, trans like this race only, no downshifting ever, and even though you can shift without the clutch after 1st, not recommended, and Joe got mad at me for doing it, but still did complimentary warrantee repair.
If you want a relatively inexpensive serious race trans, I imagine you could place wanted add here and the B site and find an input shaft. I have seen evidence that there are at least half a dozen others here that ran Liberty stuff back in the day. And then I would send the gears to the Liberty Co. for renew service.
