Believe me you are not the first person facing this delima and you are bound to get many opinions on what to use. You have to deside what you want to truck to look & ride like when you're finished. If you have limited skills another less expensive option is the narrowed IFS from a 73-87 full size pickup. I've done this swap on my
'50 3600 and it's not dificult at all to do and cost's considerablly less. But when its all said and done, do what pleases you.
