Rear End Measurement Help
 

Happy Friday everyone and was curious if I could get some help.

I'm currently sourcing a 73-87 SRW 10bolt (8 Lug) rear end for a new project. I was curious if anyone knew the measurements of WMS to WMS and Spring Saddle/Seat. I found one about 2 hours away but the owner is in his 80's and said he is unable to get out and measure it for me.

I've searched the internet and found the measurements for a DRW Dana70 but nothing for the SRW 1 Ton rear ends.

I appreciate any and all help!
