type 63 chinese aa tank

yes the turret is rather squarish  just the guns and int. would be hard

it looks similar to the russian ZSU 57-2 if you could find the AAA system you could use that as a start on the turret

these sights may be handy in finding the AAA systems I hope this might help

Wow, it's been ages since I've posted on FSM, but I figured I'd comment on this thread (despite it being six years old...)

I'm looking for a Type 63 conversion as well (or at least a twin Russian 37mm mount in 35th) .  The vehicle pictured above that was sitting at Aberdeen is now in my collection at the Army Air Defense Artillery Museum at Ft. Sill.  The vehicle is a beast.  Very rudimentary.   Jagged welds all over it, unfinished doors just cut into the turret, it'd be a nightmare to serve on!  

Anyhow, just wondering if anyone had any idea if there was a conversion out there...

Thanks!
