Wilwood builds a 9" conversion using the Explorer style rear brake setup at about $600. My F150 also has the same type e-brake, also on an 8.8.
Even if you can find the earlier Wilwood conversion - it too works well . See the attached - this is on a '57 - 9" diff.
The only problem with this is 15" wheel clearance - or lack of -you would need a 16 or larger wheel (and especially not a 14 like the '68 has. This particular setup of mine is reversed side to side from normal installation to allow cable clearance on a '31` Ford 'A'
Also, some mid seventies Granada's and Lincoln's had a very nice but fairly complex disk brake setup - if you can find a non rusty good one. I believe this one may be about the right width to fit under a '68 'stang without shortening - 56/58" sticks in my mind when CRS doesn't take over plus it has all of the advantages that all 9" diffs have - easy change out of ratios.
