    Looking for old colt SP1 update parts

    So, a good friend of mine has an old colt sp1, that has the janky front pivot screw/pins, not the current slide out type. Does anyone know where to get replacement parts, to make it compatible with new uppers? ie. the small push pins.

    Current colt SP1 value. Very decent condition

    Saw a very clean example of a slick side SP1 today in my travels, looking correct and complete ( did not examine barrel). It would be under 2 grand, even with WA sales tax. Should I go back and get it? It's not really my thing, but I know they're drying up.
