I spoke with Fatman and they said they can build an IFS for this truck. However, they said the IFS would not be appropriate if I want to keep the truck as a 1.5 ton. They said their designs are geared more towards street rods. I'm not really wanting a street rod, I want to be able to use the truck as a truck so I'm probably going to eliminate the IFS as an option.
I have read Grigg's notes on the P30 axles a few times. I think the P30 would be a good option or possibly one of Randy Domeck's kits.
