'86 420SEL Sunroof Reassembly Need Advice

[Randy]

Hi, I got a big box of parts from Phil on Friday (Thanks Phil); now in attempting to reassemble the sunroof I need some advice from someone who's been there: I can get each slide-lift bracket in the track by starting from toward the rear, then slide it forward to the stop. The three 8mm bolts on each end of the bridge are pretty tough to get in place that way, though. Also, what is the best way to get the rear rain gutter in place: push the bridge and brackets back, then place the gutter and pull the brackets forward, or? Also, need advice on the adjustment of the bridge with the side brackets.
Have a little mercy: mine came apart in pieces, so I'm starting from semi-scratch.
