You have both guns there and you gotta ask? Oh silly man,,take them out and try.
They have the same width, and the trigger lever will be in the same spot too actuate the trigger arm on the lock. Trouble is the inlet for the single trigger is for the entire trigger guard and trigger. You'll have to inlet the N.E. stock for the rear of the Ren trigger guard, or you can just leave it on top and drill a hole for the rear screw.
Another problem you might run into is in 98 they started to use a through stock tang bolt,,the front tang screw goes all the way through to either the single trigger houseing or the front of the double trigger style trigger guard. If one has the through stock bolt and the other doesn't well you'll need a double trigger guard with a proper hole..
In any event, you'll not know what you have until you take'm apart,,It's easy,,go for it, there are no springs that will go flying across the room or nuthin, just simple screws.

p.s. you can see a threaded hole on the front of the trigger guard IF it's a through stock tang bolt,,if that's the case then the front tang bolt on top the gun is what holds the trigger guard in along with the 2 wood screws in the guard itself..
