For the brake reservoir, I only drilled out one existing rivet, if I recall. I don't think the spacing of the reservoir holes is not the same as the rivet spacing.
I may have misspoke, but I think is is the firewall doubler shown on DWG 19 that you don't need if you're installing the fuel injection high pressure inside pump. I'm referring to the F-601Z Aux Fuel Pump Doubler shown in the lower right hand corner of DWG 19.
The doubler shown on Op 32, if I am reading the plans right, is needed even with the FI pump to strengthen the firewall where the fuel line passes through.
If I'm understanding this wrong (it's happened, let me tell you!), please set me straight..
