i counted 16 spotwelds, in groups of 2. i got halfway through the first with spot weld drill bit then it shat itself. repaired it and tried another and it shat itself again.
Got the grinder out and butchered with a cutting disc, was out half hour later.
You can see all the spot welds from under the bulkhead inside the car. I could only see the frontmost ones from the engine bay, even after sanding.
figured i might as well cut the lot out since there were the odd little pinprick hole where rust had got in and i plan on some subtle bay smoothing. Battery in the boot and flat panels ftw
