Hay SixGun,
I have a pair in my vaqueros. Really nothing to. There may be a tad bit of fitting but the instructions from Power Custome are easy to follow. Have you taken your rugers apart before? Also, be prepared to modify the transfer bar so the gate will open @ half cock. At one time I also put in the free spin paw, but later took it out and put to original back in. More of a personal prefference. feel free to e-mail. I can pdf the the instructions and e-mail them to you if you'd like.
