Guys,
I have found something at
http://www.rockauto.com.
This is the description:
ACDELCO Part # 45U0184 More Information About this Part {#89029366}
JOINT KIT,F/AXL Prop Shaft RR UNIVERSAL PREMIUM; DIAGRAM V, POSITION 1; w/4WD; W/DOUBLE CARDAN CV AT TRANSFER CASE, 2 REQUIRED
I got it in their parts catalog under "1980 TOYOTA PICKUP 2.2L L4 : Drivetrain : Universal Joint"
Could this be the right one?
Danny
