Default CPT Drag link on a 2WD Scout 800?

I need to re-do the steering in my '67 2WD Scout 800. Actually just the chassis is from a '67 2WD Scout, the body is a fiberglass Ford hot rod (google a "Glassic" for more info). The ball stud and drag link are worn out. I'm looking at the CPT drag link, or possibly even the whole tie rod + drag link kit, but I have some questions and some problems. My car is much lower than a stock Scout. The current pitman arm is a ~2" rise, vs. the 2" drop of the pitman arm that comes with the CPT drag link. Can I buy the CPT drag link without the pitman arm, and can I just press out the ball stud in my 2WD pitman arm and reuse my existing arm? Supposedly the taper of the stock pitman arm after pressing out the ball stud is the same as the taper in the tie-rod attachment. Since the CPT drag link is advertised as fitting the stock tie-rod, would it also fit my existing pitman arm after removing the ball-stud? If necessary I can also ream my existing pitman arm to 7* if the CPT drag link is designed to use a standard 7* tie-rod end (maybe the ball stud is already a 7* taper?).

Second question, given the lower steering geometry, I assume I would not need the 2* shims for tie-rod clearance if I went with the whole kit?

We haven't installed one of these kits on a 2wd Scout yet. If I remember correctly, the 2wd tie rods are wider than the stock 4wd ones. It has plenty of adjustment so that won't be an issue, but we would need to verify that the draglink is the same length. The 4wd ones are 21" center to center.

I believe that you are correct on the taper being the same from the pitman arm vs the ball stud. If so, we can omit the pitman arm and swap out the tie rod ends so that the tapers are the same on both ends of the draglink.

If you have a decent amount of clearance between your stock tie rod and the leafsprings currently you should be good to go. The new tie rod moves down more, so it ends up awfully close on the 4wd axles. Thanks.

I'm not sure if this is the way all 2WD Scouts are done, or if some of this is specific to the 'Glassic' chassis, but mine is spring-under-axle and I have what looks like plenty of clearance between the springs and the tie-rod. Also pictured is the weird pitman arm with the 2" rise.

I need to redo the whole steering assembly, including the box, which I'm looking at changing to something with better parts availability anyway. If I go with another box, what size pitman arm hole should I be looking at to fit the drag link? Is it a standard 7* taper rod end?

It does look like you have plenty of tie rod clearance, so no need for the caster shims.

The tie rod ends we use are all the same degree of taper, so we can ream a pitman arm to fit different ends. If you find a newer manual steering box, then we can supply a flat pitman arm for it if that would fit. Otherwise your existing pitman arm should work on it if you can grind and press the ball stud out. Thanks.

Michael, here's my plan for the steering box (see attached photo). It's a '63-'68 Corvette manual box. Same input and output shafts as a Ross SE54 (3/4"-36 input, 1 1/8"-36 output). In the picture there's a manual Scout pitman arm lossely fitted to the Vette box, which is almost correct but the draglink needs to go above the arm, not below. Only real difference to the Vette box is the bolt pattern for the mount, and the fact that it's ~2" shorter. Since I already have a 2"-rise pitman arm I would need to go to a flat pitman arm with this box. Can you supply a flat pitman arm, roughly 6" center-to-center, drilled top-down so the draglink end is above the arm? Possibly the S80-800-PITMANARM-0 would work if it could be drilled top-down?

I just took a look at the flat pitman arm and we can ream it for the next size larger tie rod end from the top down. It would have the ES150's on both sides of the drag link which are readily available at the auto parts store if you needed replacement in the future.

Great! Last question is why the S80-800-PITMANARM-0 pitman arm says "not recommended for 4 cylinder applications"? I have a /4 in my scout, is there something I'm not aware of?

This would be a factory Scout application as it doesn't really work with the steering box location of them. Yours is a bit lower, so that disclaimer doesn't really apply. Thanks.

Michael, almost ready to start ordering parts. I noticed that although I have plenty of clearance at the springs I have very little clearance between the wheels and the tie-rod ends. Are the ends on the CPT tie rod any larger around or any taller than the originals? Also, I have very little clearance to the shocks at full steer. How much larger is the CPT tie rod? I can probably back off the steering stops a little and gain some clearance at the shocks, but not much. I may just have to keep the stock tie-rod and get the CPT drag link (assuming that's an option).

Without seeing your tierod ends up close to match we cannot promise that ours are the same size but they are the smallest we have compared to other tierod ends we have on hand. As for the shock clearance an adjustment of the steering stops will prevent it from hitting. If you decide to keep the stock tierod and only run a new draglink we do offer that - CPT - Crawler Proven Technology Pitman Arm and Draglink Combo for 1961-71 Scout 80, 800, 800A, 800B

Jeff, thanks for the response. I can measure my existing tie-rod ends in the shop tonight and see if it's at least close to what your CPT tie rod is running.
