found out that the bigger fly wheel was of a g16b motor my mate had a 1.6 put in his hard top bout 10 years ago and got the old 1.3 back he sold the hard along time ago and the 1.3 has been in storage since any way when they gave him the 1.3 back they bolted the 1.6 flywheel back onto the 1.3

we never realized

any way we ended up getting the right sierra fly wheel still a shit load thicker than the gti on
we only realized the when going through his old starters and found one that had been grinded to suit the 1600 oh well lesson learned
