Welcome to the forums - and another welcome to the '64 Overlander club!
You'll find a treasure trove of information posted here - familiarize yourself with the
Search button above. I looked briefly in my saved threads, but didn't see one on shocks. Here's a couple good links for similiar trailers though:
A 63 for me! (many good ideas for your new to you Trailer) 12v bulb numbers for 1964 1964 Overlander, San Leandro, California A New Challenge-1963 Overlander rehab project My '64 Overlander Adventure
The last link is mine - I don't know how useful it may be, but you may find it amusing at least
. And while the next link is a for a trailer couple years older, Carlos has got some talent you've just got to see.
