Yep chevy d44 is passenger drop. Also the waggy axle is a horseturd axle so the best thing to do would be to get a hp44 out of a 78 ford half ton and make it work with the calstinky kit. The way the calstinky kit attaches to the axle is a poor design and you WILL break the bracket off the axle. Have a shop do the sas for you without the calmini kit if you want to do it right
