Ya need a barrel with 20 TPI for any Antique SAA colt.
I ran accross Dean's site, but I'll admit I ignorantly stopped when I used his search feature and nothing showed up under cylinders. Will get in contact and see what's what.
Thanks guys

They don't list prices - you will have to call them. I haven't ever dealt with them - so can't speak for their honesty.
US Firearms Manufacturing also sell parts - I THINK that they are interchangeable with the SAA - but you will have to check - again - fairly pricey:

Again - I haven't dealt with these folks - so can't vouch for them.
