why only 6 bolts (Rotax 582 Exhaust)

[LSaupe 123]

Riddle me this, why do they (Rotax) leave out the inboard upper bolts on the exhaust manifold for the 582?

These allen head bolts are next to impossible to get in.

Studs with nuts are a good fix but still a fiddle

They only need 2. 3 will warp the flange. It's made to be ran right side up or upside down same as a gearbox. Checkout JBM industries for a much cheaper better than Rotax gasket.
