Horn, cowl bolts, Flex-a-lite fan....and more questions

[scoyote]

OK....getting down to the stuff we cannot remember ;-)
1972 Blazer.....almost...

1) Where does the stock horn go? I took lots of pictures before we tore it down but I can't find one showing location and I browsed quite a few builds on the site and didn't see one so I gave up and figured I'd do it the easy way.

2) Does the cowl bolt down (besides the ends) does it bolt down where the hood/cowl gasket is or is that push pins? And if it is bolts...anyone know what size or where I can get a "kit"? LMC doesn't have them.

3) I want dual electric flex-a-lite fans with thermostat controls. I have these on my Ford and I love them.....anyone else used them on a stock blazer radiator? If so...what size? Flex-a-lite doesn't list a 1972 blazer and I don't have the radiator back from the shop yet.

4) Radiator overflow ideas? Besides the stock big ugly overflow tank, anyone have something that is pretty cool looking and fully functional? I don't really like the look of the stock one.

4) Besides $250 plug wires from MSD for my HEI distributor.....what is a good and capable alternate plug wire? I don't want $40 wires on that stroker but I didn't want to spend $250 either....anyone have a good alternate?

5) Antenna......should have plugged the hole and bought a windshield with it built in but it's beyond that now and I need an antenna. So.....besides stock repro.....????

Some pretty simple and stupid questions for most of you guys but I've been searching the internet, LMC, Truck and Car Shop, GMC Pauls (hard website to find anything) and I'm out of ideas and places to look.

Any help?
