Engine sheet metal not fitting

[HUNGVN361]

Hello,

Engine recently installed back in car with issues in gap between sheet metal pan and seal. A large gap ..3/4" at least. I've try to force it in between the seal but is not working. What could be the cause? Any help and advice would be much appreciated.

Thank you,
Bao

The rear tin relies on an upright support piece between the stock muffler and the tin. If you don’t have a stock setup you can easily fabricate something.

So , i'm not fully understand... when I disassembled the engine to rebuilt , i don't remember seeing this upright support piece... so fabricating the piece is my only option?

Bao,

Google "Porsche 912 stock exhaust" or "912 muffler", or "356 muffler" or something like that.
There are 2 holes in the sagging tin, (one on each side) for 2 brackets that mount on the muffler
(stock muffler)
since you have an "extractor" exhaust (old school term) you'll have to fabricate a couple
of pieces.
Please post photos, I'd like to see how you do it.
