Where have all the Magnum parts gone?

Hope this works. I don't see Jadahrabi" pic just a link to it that I now can't open. I have an M1 like Jadahrabi shows and then there's this one. Both taken from a thread "a page down" by "six barrel Bill" about running v belts on a magnum.
I may have to find one like the 2nd pic due to wanting AC on this build and 80s truck brackets possibly not wanting to work on the first one.
The links both worked. His shows the Magnum intake bolt pattern with LA thermostat and bypass hose and mine shows the Magnum intake bolt pattern with Magnum thermostat and bypass hose locations. I know in the single plane versions they also had LA intake pattern with Magnum thermostat and bypass hose locations. There were some interesting parts available for a short time.

Ford small blocks and Chevy small blocks (not LS please don't start on those, I want nothing to do with them)! haven't been built in even longer yet stuff is still a dime a dozen for them...
Something that's always pissed me off.... As in how many people don't even acknowledge Mopar exists
The GM and Ford stuff is STILL available new from GM Performance and Ford Motorsport. Their popularity justified keeping some of those parts in the catalogues long after they were used in any production vehicle. Chrysler always discontinued parts as soon as they could. It's a shame really, because the M1 single plane intake was a really good part and back around 2000 they were only about $199 or so. Now some clown has one on ebay for $1500. It's not worth anywhere near that much, but you never know what someone will be willing to pay so they get posted like that.
