Cost to keep stock front suspension and brakes

[RamboHern]

My front end is pretty much completely shot. Half of the parts are missing and some of the back plate is rusted away. I was wanting to know what would be my best option on getting this thing set up. I'll keep the solid axle and leaves, but want to go 5 lug on the front. Should I just go with a disc brake conversion or what are my other options? Also, if I do get the front disc brake conversion what are some good sites to look at?
