I was just referring to the style of dust boot. It seems as though the “cap” style could possibly lead to more dirt/debris to come in contact with the tie rod grease as opposed to say the pressed n type that came on the vintage tie rods. The Moog one shown below is showing the cap style I am speaking of. Wasn’t sure if it was anything to really be concerned about or not. Definitely don’t plan on going with cheap components.

The MOOG caps fit pretty tight.  Remember, they get held in place pretty tight once the tie rod gets bolted to the spindle.  I think the newer design works fine, as they provide more movement than the old pressed on seals.  You won't be disappointed in MOOG.  It is better for a little leakage to occur than to have a fully greased tie rod boot burst from internal pressure.

Good point on the internal pressure of a sealed boot. Something I didn’t consider.

I wouldn’t worry too much about it. There’s very little if any pressure externally that would force junk under the boot. About the only way for debris to get in is if there’s a crack or part of it missing. Just buy top quality parts and you’re fine.
