Great piece of information.
Already looking for a long time to change the gears of my 1948 Chevy 3600.
Now the only challenge is to find an Eaton HO52 center section, from a ’68-’72 GM 3/4-ton with automatic transmission.
And in the country where I live (Nl) there are no junkyard where you could find something like this.
So, need to find it in the US.
If there is someone out there who could help me on that then please send me a PM. New or used, as long as it is re-usable. Thanks.
