I've never seen that style. When I did my suspension I used the ones like Fierosound posted and they worked great.
If you look at the Rock Auto Website the cam bolt you show is only good for 1 to 1.25 degrees. The Ones that Fierosound posted are good for up to 3 degrees. Look under the "Alignment section" for the Spicer part.

Plus / Minus 3 Degrees Camber; Single Offset
MOOG Part # K90476
Rear Suspension; Lower Strut Mount; Fast Cam/Bolt Kit;
adjustment range from -1 to +1 Deg. MOOG Part # K928
Rear Suspension; Lower Strut Mount; Problem Solver; Magna Cam/Bolt Kit;
adjustment range from -1-1/4 to +1-1/4 Deg. The other thing that helps get the alignment dialed in when you lower the suspension is the adjustable upper ball joints for the front:
