some rough pics of 4104 spring brake install.

[zubzub]

I find it hard to remember  get under the bus with a camera when I am in the middle of a job, so i only have "after" pics.  This is the spring brake install I did. The two relays...

....if I were to do it again I would get a relay that did both functions, cleaner install as it's a little tight in there.
springbrake can near the firewall.

There were maybe 2" to spare but....the captive bolts just make it in when the springs are pushing.
and finally a picture of part of the dreaded all aluminum suspension arm
