The Question: S10 or No S10

[a5Ben]

I'm still laying out the plans for my 49 3600 and wanted to get some opintions ( I know there are many)

I am down to three plans for the truck.

#1.
Weld in an IFS (Scott dansforth) with S10 suspension
Swap rear end
drop in a 350/700r4

#2
MustanII front end
Swap rear end
drop in a 350/700r4

#3
Put the body onto an S10 rolling chassis
Add spacers to the rear end or swap it
drop in a 350/700r4


For option #3 I have located a 97 extended cab short bed rolling chassis for $275 with wheels/tires, all suspension, gas tank and steering column. Right now I'm leaning towards this option because I think I can get the truck on the road faster but I wanted some ideas from those of you have been through this a time or two.

Thanks!!
