mark, the primary difficulty i faced during the install was the small spaces in which to place the various parts. once the cluster is removed, that is your only access point of any size at all. i had trouble getting my hands back in to the areas where i needed to connect the hoses and attach other brackets, route the wires, and hold everything together with one hand while trying to tighten everything up with the other. if you have the manual available, that will be to your advantage. also, have a small jack on the passenger floor to hold up the assembly until you have all the bolts started, as it's difficult to be on both sides of the floor pan at the same time. also, remove the windshield completely, so as to draw your cutout pattern accurately.lastly, and this is the really important bit, complete the job before you're old and arthritic. i seriously considered taking up heavy drinking during this job, and i've never drank in my life. good luck, colonel--by the way, when we came out of the nam, our brigade retired to benning in oct 70, and i was one of the color party that brought the flags home in a C141 from bien hoa airbase.
