82 K5 Blazer Heater Box GM Part # and Interchange

[Bohemian]

I need a heater box for my 82 k5 blazer with factory heat & air.

Need the GM part number & interchange list for what years of c/k Chevy's that I can get one out of.

Thanks in advance.

81-87 1/2, 3/4 ton pickup
81-91 Blazer, suburban and 1ton crew cab will fit you 82. Use LMC truck for reference to find part numbers and see what is not available new anymore. Try GM dealers.

I'm not sure when it came into production and back out again, but if you've got that gear synchronized plenum, lots of luck!

That's what I have in my 86 K5, and it's miserable if you don't have the chart to set the gears into the right positions.
