6.5TD with a/c.... pics/info

[madcow75]

I am in the middle of doing a conversion on my, which once was a 1976CC C30 and now a K30. Origanally it was a non a/c cab but want to convert it to an a/c cab. I have a 6.2 diesel with a 6.5TD top end. Has anyone fit the 6.5td in with the a/c in their 73-87/91. I understand that it will not fit without some modification. Any modification info would be nice. Pics would be even better. I have read before an s10 a/c box needs to be grafted on? Also read a possibility of a van a/c box. But I have not really found any solid info or someone with the experience on doing this conversion. . My cab is currently striped and on a dolley ready to prep for the a/c.
