Hi Bill,firstly welcome.
I've never been a fan of cut 'n' shut chassis. JMO

There's a huge choice of aftermarket IFS' available.
The only real factor is the depth of your wallet,you also need to consider what you want from your truck regarding load capacity.

If you're just looking for a cool old truck to scoot around in fine,but if you want to work it,personally I would stick with and rebuild what's there,with upgrades to the brakes etc..
