4 speed H42 1976 land cruiser ( very similar to Chevy SM465)
I already have it converted to Chevy in my land cruiser. So I just need to adapt the bell housing to the benz.
I am trying to do similar to this.
http://www.4x4labs.com/products/diesel-conversions/ this setup is for a auto IIRC. and the cost $1k for the adapter. It's well done but I have the time and inclination to fab my own adapter .
