Done a few, not really all that difficult. Should also add in a 4 or 6 point roll bar for strength and rigidity. It really depends on your fabrication and welding skills and level of experience on chassis work. I can say it's easy cuz I've been building cars for 40 years...... if this is your first undertaking of such proportion, then it would be very involved and have lots of "opportunity" for major mistakes!!!!!
