Is there a part number for these trucks you mention?

Thanks for the info. I guess the next step is to go see what the hobby shop in Wilson has in stock and what they might have that I can use. At least now I have an idea what to look for. Thanks again and I'll keep you all posted.

thanks for the replys guys! Desert, you mention that if you were to do that many cars again, you'd go for a direct replacement. Is there such an item as yet out there or do I need to go to the 1129's-1133s? Which of these would be the longer coupler? And RGW, do these "dummy knuckles" magnetically connect and disconnect?

I've looked on here for some time and have yet to find an answer to my question of, "Is there any magnetic couplers that will go right into the T shank rapido couplers without having to replace the trucks? "

I would soon like to be able to couple and uncouple cars and right now all of the ones I have have Rapidos on them. And it seems that the hobby store near here has mostly newer style magnetic couplers and those wont connect to what I already have. I really don't want to replace all the cars I now have.

Thanks for any answers!
