Tie rod issue

So i changed the front end from drum to disc, using SSBC system. also changed the upper control arm to a QA-1, and got the tie rods in the kit. I saved the sleeve to reuse and measured the combined length of each side of tie rods. when I went to put the new ones on, there wasn't enough thread in the sleeve for my comfort level. Almost like the old rods had longer threads than my new ones, but I tossed the old ones before I could compare them. Anybody run into this?
