4 point and standard seat?

Hi, i have just got my new Luke Pro 5 points, can i use the passenger one with a standard seat (without the 5th strap)??
Cheers

 

how are you going to mount it?

 

where are the shoulder straps going to go?

 

Ive seen it done , shoulder straps between the head rest mounts - wouldent vouch for the saftey aspect of it though especially with the standard seats being hinged ,in a nasty accident you could end up quite abit shorter .

 

I think i will leave it until i get another bucket seat, got a cg lock for the passenger to be getting on with. Thanks for looking
