4020 tie rod adjustment widening front end?

Trying to widen the front end of my '65 4020. Have be able to pull out the axle, but cannot get the tie rod to lengthen. It looks like there are 3 pieces, the outer main one that goes from end to end, a middle "pipe" and the smaller "pipe" that holds the actual moveable tie rod end.

I can get the smallest "pipe" to move about a 1/4", but cannot get the middle "pipe" to budge. Do the "pipes" just pull apart? Do they need to be twisted or how should I move them? Soaked them with PB blaster overnight hoping just seized from rust.

Second question is I'm widening each side one bolt hole or about 2-3 inches. Do I move both the middle and smallest "pipe" on the tie rod equal distances, or does all the adjustment come from the smallest or the middle "pipe" on the tie rod. Obviously the bolt holes need to line up to re-install.

Final question is are the rubber dust covers available separately from the tie rod ends? Mine are worn out, but the ball sockets look and fee good.

Thanks.
 
Rosebud on your torch and get it red hot. Walk away and come back when it cools. Should be loose. Heat turns the rust bond into powder. Just try not to get the ball joints hot or on fire
 
Lengthen the tie rods the same distance as you move the axle. Where you lengthen them doesn't matter as long as they are together by a few inches at each joint. Doesn't hurt to check the toe-in when done. 1/8 to 1/4 inch toe-in. The rubber boots I think you can get from A&I but I don't have time right now to look.
 
You may have a fit getting those tubes to telescope. I've had a couple situations where the rust didn't look that bad but no amount of heat, beating and banging would loosen them. Many times by the time you heat, bang, vise and pipe wrench them they're a distorted mess. In those cases I just gave up and bought new ones. New ones are a treat as they turn and telescope like butter.
