Including dissasembly, the trips back and forth to hdwr store getting all new grade-8 bolts and of course cleaning-up things along the way, spray paint here and there and breaks I would say make a full day out of it. I'm sure they could be slapped on more quickly but just keepin it real. I found the most challenging part to be getting the forward leaf spring mount plates, corresponding fame holes/nuts and new sub-frame connector holes to all align. Take your time with that. I used a bottle-jack, c-clamp & pry-bar to twist things into position. I also used new grade-8 bolts & washers here which that were a little longer than originals. Now many people will tell you to use a solid body mount vs. the poly or rubber to more firmly connect your subframe connector. This is good advise. I compromised and retained upper poly bushing (between existing frame and body and the made my own solid bushing to firmly clamp the subframe connector to the frame. I'm not a 700hp 1/4miler Mario Andretti so wanted to retain some small amount of cushion between body and original frame. But I do think that using the solid mount that I fabricated below firmly plants the connector to frame. I made it out of some very large thick washers that I got in the Nuts & Bolts section at teh True-value and had the open them up a little in the center to fit the OD of the steel body mount. This may be too much info. and more than necessary but just sharing my version. of it.
