Every now and then I see a 742 or a 7400 that is priced pretty cheap..
There's good reasons for that....
Ahlman's in Morristown, MN, used to advertise that they converted 740/742 series rifles with damaged guide rails into 760 pump guns. I don't know what they charged or even if they still do it, but the answer is only a phone call away.
Yes they did - but I'm not sure they do that any longer.. But, at the time, I believe the cost to convert was $175....
I'd be interested to hear if they still do that, and what the cost would be..
