I'm in the middle of replacing every a/c component on my truck, and I'm a little confused about which orifice tube to order.

Rockauto lists a few different kinds...

ACDELCO Part # 155612 {#15097129, 1531963, 52477004}

DENSO Part # 4754103
Front A/C; OE recommended replacement part. (Only 10 Remaining)

ACDELCO Part # 1550121 {#19189842, 89032869}
ORIFICE,A/C EVPR TUBE 2 WHEEL DRIVE; FRT UNIT, EXC RR AC, OPTIONAL AUTOMATIC ADJUSTING ORIFICE TUBE FOR NORMAL CLIMATES (105 DEG-)
ORIFICE,A/C EVPR TUBE 4 WHEEL DRIVE; FRT UNIT, EXC RR AC, OPTIONAL AUTOMATIC ADJUSTING ORIFICE TUBE FOR NORMAL CLIMATES (105 DEG-)

FOUR SEASONS Part # 38905
Optional Automatic Adjusting Orifice Tube for severe climates (105Degree+); w/o Rear AC; Front


The only visual differences I see is the 'yellow' is yellow, the others are white, and the last 2 are half white/half black.


The one that I see in the lower tube in my old condenser is black.

which one do I buy?!
