Hi Alan,sorry to hear your having "One of those days!" I'm sure most of the other "Bolters" have had days like it!
Looks like you've got some Major surgery goin' on there!

I hope you took some carefull measurements before the first incision. Messing around with windshield aperatures can be tricky.Just make sure everything goes back in the right place!
I you plan to replace the windshield, use the old one as a template when re-aligning the metalwork. There's nothing worse than getting your pride and joy back from the paint shop to find your Window doesn't fit! ,My buddy in Va. did this with an Austin Mini and had to get the windshield 'chopped' to fit!
Re; The rat sh*t,I hope you've been wearing a mask!

I suppose any good quality disinfectant would work,just be thorough!
Keep your chin up mate! You'll get there!
Regards Jock

Remember.... Measure twice,cut once!!!
