1990 Technodrome playset question
 

I recently managed to get a good deal on a Technodrome. However it's missing some pieces (I ended up just ebaying them) and the shells sometimes come loose. I noticed there's some screws on the corners and some slots on the base, but they don't really fit if the shells are on the hinge. Am I missing a part or did I misassemble it?

Also, I am missing a pair of "mutant manacles". I have no idea where to find a pair as I already checked ebay and google. Is there a place that makes repro parts or something?

Looks like you have it put together correctly. The bottom of the shells gets warped over time, so those pegs on the corners don't line up right after a while. They don't really matter when it's closed anyway, they are there to hold half of the shell when it's open.

Here is a good place to get pieces/parts:

Little more expensive than eBay on average, but much more convenient.

Not with the 60% discount...

Darn only one mutant manacle. No point just buying a single one.

Also too bad about the Technodrome base getting sort of warped. I was thinking about getting longer screws or something, but it doesn't matter too much since it closes together just fine and as long as you flip the feet out, the dome halves stay up okay.
