Air Deflector that fits right?

[ninety6]

1986 c10 Silverado RWD

The original part number (stamped on the back of the factory piece) is 14033331.

I believe the correct replacement part number is 15569084 / GM1092122

Tried the one from Amazon ($25), it doesn't fit. I read a view from summit that their version doesn't fit either. Basically -- it's about an inch too short, and none of the bolt holes line up. Yeah, i could drill new holes, but i'd rather buy a piece that fits right.

Does anyone know if the LMC one fits correctly? Part number 38-7403...

Apparently no longer available from dealers (no surprise there)...

I don't mind paying more for the LMC one ($50 shipped) if it fits right... Anyone know for sure?

Here's some pics of the amazon one that doesn't fit next to the original. Every hole is off by about 1/2" or 1"...
