Began by modifying upper engine mounts, 6-B-6-4. Had to remove some material at upper outer corner towards the firewall. Enlarged mounting holes in longeron to fit AN3 bolts. And countersunk the 2 rear holes. Use M24694-53 bolts. Temporary drilled holes in firewall up to 6mm. Primer and paint engine monts and also main gear support 6-B-11-4. Deburr and primer doublers 6-B-16-4L+R, and side panels 6-C-1-1L+R. I had to make some cutting in fwd end of panel to make it fit.
