Any idea of what is the best way to lock this tranny 3speed H pattern with reverse.

If it's a Peerless 600 it should have the same differential carrier as the 801 series and what not. Matthew D and Sadeoo have locked their 801 series transaxles using strait axle conversions. Maybe you could check their build threads. P.S. You have yourself one tough transaxle my friend hahaha!

I don't think the 633's are made my Peerless are they? I thought they where manufactured by Roper.

The 633 is made by roper. They do not use bevel cut spider gears, that means you cannot use some of the popular methods such as adding gears to lock it. Its a different configuration, not the same as a peerless.
If you want to lock your 600 series peerless i would use fozzy or doc lock with straight axle. If you go with a doc locker keep your wheel spaced closed to the trans so you dont bend an axle like me... Also be carefull with the keystock that you use, i had to weld my locker because my key broke. Checkout my yard man build if you want more info on the doc locker for that kind of trans. The case looks dofferent but the dofferential assembly is the same as a peerless 600.

There are some video's out there where people have flipped the orbital gears to lock a Roper 633. There are people with differing opinions about this whether it makes it weak or not.
