Just recently I came across a Spectrum Coach #3764 Item No. 89003.
I know it's very old and it could have been a kit.
I'm experiencing a problem attempting to replace the couplers[horn hook] with knuckle couplers.
Can anyone shed any light on how to go about this or is there a knowledge base to reference how to solve my problem.
Thank You in advance for any and all information that you can share...
If your coach is Spectrum then it most likely originally had a knuckle coupler. Of course if it is in the range of 25 years old then it may have originally had horn hook couplers. The coach was not a kit as far as I know, they never made them as kits.
If all else fails, remove the existing coupler box/assembly and replace it with a body mounted coupler box (ie Kadee). Bear in mind that doing this will require you to have about 24" minimum radius.
