64 3/4 8 lug rear end swap "Eaton out Dana in" Opinions?

[Texasdeere]

I have a 64 C20 with the Eaton HO52 rear with 4.56 gears. Originally I was going to put in a 700R4 to replace the powerglide to get the rpms down. I am thinking now about a Dana 70 with the 3.54 gear set instead. I know there were a lot of these in 3/4 ton Dodge trucks and also in some 70's chevy 3/4 ton trucks.

I think some of the Chevys had the Dana with coil spring set up but I am not sure. This might be good for less fab work. I am likely going to have someone do the work for me once I find everything needed.

Anyone done this before?

Thanks
