Okay I talked the junk yard down to 100.00 for a 88 dodge caravan roof smooth no roof rack... they will cut it 3 inches down the pillers so I have a complete roof.... since the car is complete and I am just replacing the center protion of the roof where at one point in time was no roof do I need to brace the car when I cut the roof off? what is the easiest way to get the new roof on as far as measuring cutting etc? and should I just use tack welds all around the roof spacing and hammer and dolling them till I finally get it welded in ? I was probably going to tack all over the place none side by side in hopes of not warping this roof and getting a roof that looks a hundred times better than the one on there now. any help on how to do this would be appriciated I have looked through past posts but don't seem to have a whole lot of info on getting the job done from beging to end, if there is anyone that has done this and would like to give me adive on how to do so I would appriciate it greatly

thanks,
simon
