GU Driver seat replacement

Looking to change the drivers seat in my 2001 GU ST. Want something that had height adjustment and can go lower and if possible back further as I'm a bigger and taller bloke.
The newer series GU have height adjustable seats. Are they a good swap? And do they only straight on??

From what I hear people usually put in Ford falcon xr6 seats never heard of upgrading to the newer patrol seats, with no one replying I’d say it might not have been done before
