Wanted OLD Questar Legs Wanted

I was delighted to throw some money in for a trade last year to get pretty clean legs for my Questar 3.5. Now, prepping for the big eclipse safari, I discover they are shiny and clean but also slightly larger diameter and will not fit my base! They are the newer "screw-in" type. Can anyone point me to a set of the old push-in type? I think they were used until about 1980. I am of course willing to trade! Thanks--Chas in Dayton
