Hello,
We have a 1963 Bambi. I am basically clueless if our Goucho is similar to yours, but I rather doubt they made great technical strides between 63 and 67. Anyway, my husband rebuilt ours to make repairs when he had our trailer apart. On page 24 of his thread (Floor replacement by NorCal Bambi) he has some pictures of the slides, etc. Scroll down.

Hopefully they will give you some information and insight?? Good luck with your project!
