Youv done the correct thing with the rears.
But the front is a bit of a fiddle. 2 ways really.
1. Chop the sub frames up from both seats and do a bit of welding. Then 1 set of seats is fecked and the gti seats wont ever go in a 3 dr agen.
2. Do what i did. (but oposite way round 5drs into 3 ) is to make another bracket out of angle iorn and bolt it to the OE runner on the 3dr seat then bolt the angle iron to the car . This way it fits both.
Second thoughts option 2 may only work with 5dr into a 3dr and not 3dr into 5dr
