Yes you can, but you need grade 10.5 or higher on the bolt, and I don't think any one knows the size and thread pitch, but you can have a store match one up for you.
Going to need a truck shop or specialty store for the bolts..
These are a little long, but its the closest you'll find and you can always grind them down a little and shorten them (if you bottom them out they will hang down about 3/4" below the torsion bar bracket). I used these exact bolts on my 97 Explorer (same suspension, yes they will work for a Trac).
Brad ... it shows it as a 120 mm bolt ... will the 110 mm work better so it won't hang down below the torsion bar bracket ? The only difference between the two are the length (120mm vs 110mm) and the weight (.2244 lbs vs .2400 pounds) ....
