Engine Protector Bars Fitment On 865 T100

I have a nice shiny set to fit but of course no instructions.
I note that the frame has a bottom rail secured with two large Allen bolts which must be removed.

Plan to support the engine with a trolley jack first. Should I loosen and remove first the front engine bolt and then remove the frame Allen bolts before fitting the chrome crash bar and re-inserting all the bolts?

 

Thx DD. I have found the instructions online via Triumphs website

Thx for the quick response thought. Much appreciated
