I have just completed my firewall and am ready to mount it to the jig. My question is that obviously the top mount holes are there as they were already made in the firewall, but at what stage do I drill for the bottom bolts of the engine mount? Do I wait to use my engine mount as a guide or do I just drill them as per the plan now?
Another question please is that the holes for the engine mount are now only at 1/4 inch, at what stage do you open them to accept the 6/16 engine mount bolts? The reason I ask is that surely if you open them up once everything is riveted together, you will not be able to deburr the holes properly in all the material?
I hope this makes sense
Thank you for al the help
