How nice!
I've also got a rear axle with brake discs almost ready to assemble..
I also have a GA16, witch need wild cams, higher compression and soms other tuning items..
How was the instal from the GA16? Used the 1.3 gearbox i see... With an 1.6 clutch? or an 1.3 clutch..
Same driveshafts?
Used the electric waterpump? or made the original pump fit?
A lot of questions, nice work you do!
