200tdi exhaust question

In process of replacing my very rusty exhaust ppes on the 85 LR110/200tdi.

Have the necessary rear and middle pipes.

Now the question. Is there an exhaust gasket between the rear section and middle section? The sections mate together with plates that take 2 bolts. Certainly looks like one sould have a gasket there.
But i havent seen a part number or one in any of my manuals.

Thanks in advance.

use some cement....

yep, sounds like the same join as on my 96 110, no gasket there, some cement may be needed, mines blowing a little having just had it off to do the clutch, no paste to hand to put it back together with.
