need gauge advice

[IAFF2407]

this is what my intentions are, can anybody see a problem. running the 500 cad motor.
Autometer Gauges

5” #1489 speedo - programmable (elec.)
5” #1410 Quad Designer Black
3 3/8” #1498 Designer Black Tach

2 1/16” #3378 Wideband Air/Fuel A/F kit (do I need a wide band for an non EFI?)

2 5/8” # 3451 tranny temp (do I want mech. or elec.?)

the 2 other 2 5/8" on the left will be for my Vair air gauges.

I realize that the lower 4 won't match but I can't find anything together.

any input would be appreciated, (especially the ones " you're right on track Al, that's what I've done )

thx in advance

Al
