twin ibeams
ive been told that my ibeams are "ovaled out" so it would be a complete waste to have my kingpins replaced. i had everything else replaced last weekend, and i want to get the ibeams and then the kingpins taken care of asap.
i here that i can either find a good set of ibeams or have the existing ibeams welded or filled with composite material?
what are my options, and what should it cost me?

I got my I-beams and spindle from a salvege yard for $150. They are getting harder to find since scrap iron prices have been rising. Some of the guys on FTE who have installed lowered I-beams may have a 'deal' for you.

Pauly, Welcome to FTE 
and the 67-72 Forum.
A lot of us have 73-79 I-beams under our trucks with the power disc brakes. They are a direct boltup. I have 76 I-beams under my 66, bought a donor truck, sold parts that I didn't need and my steering/brake upgrade parts didn't cost me money.
You have options.

I spent $200 for I-Beams out of a 78 F350 including the discs the booster and master cylinder and power steering box and powersteering steering column and power steering pump. They bolted right into my 67 F100 with very little cussing. I cut down the F350 coils with an angle grinder to achieve the ride height I wanted. I went back later and got a Dana 60 and springs out of a 72 f350 so I would have the 8 lug bolt pattern al the way around. I made a custom spring packs by mixing the F100 and F350 leafs. The most expensive part was new rims and tires.
The ride and steering improved alot. Later I put F350 sway bars on and really improved the cornering also with a little sacrafice to the ride quality over bumps.

It seems like when I changed out my I-Beams (mainly to get disc brakes) my 67 I-Beams were cast and the 78 I-Beams were formed steel. Although the 67's were heaver I think the 78's were stronger. I also think the 78's might have had a little more caster or something built into the geometry as they drive a lot nicer and straighter.
I guess welding your old ones up and grinding them back down to fit would be a cheap and effective fix if you were to do it yourself. But for the price you would pay to have someone do this for you it would be just as cheap or cheaper to have them swap in later year yard parts in my opinion.
