Thanks..I used Dorman 610-157 on my 81 Malibu. Did have to open the holes in the axle flange a little bit for the larger knurl. I used them because I needed to add a 1/2 inch spacer. These are 2.125" under the head. The Dorman 610-259 are 1.75" under the head. The OE stud (Dorman 610-186) is 1.5" under the head
The studs you pictured are the OE length
If all you need is the .25", the 610-259 should go in the existing holes as-is
