Which adapter plate for an Edelbrock 1405?

Wow, Sunshine, you guys know everything. I really love being in this site,I learn a lot.
My truck came from las Vegas via the Nehterlands some 5 years ago. I drove it all the way down to Barcelona, ferry, and home. I've been to the US a lot, taching in NM a year, and crossing the US in a 75 caddy 3 years ago. I get prts online and try to have friends who live or work in the US bring them. I'm not a mechanic obviously but I do my best to fix my truck.

I desperately need the carved letters C and H from the tail gate, as they were covered after some accident I suppose. I'll post it some time in the future.

Yes, Mallorca is to Spain what Hawaii would be to the US, full of Germans and Northern Europeans in the summer, and the weather is really nice all year. Hot summers, mild winters. Like Gertrude Stein said in the 1920s, 'it's paradise if you can stand it'

Anyway, thanks a lot for your permanent help and teachings.
