41 pickup: I need wiper motor / switch / linkage installation tips

[504d]

Melissa Klein just rebuilt my wiper motor, and I got a new switch, but I'm having hell of s time getting all three installed and connected. I think I'm just too old, fat and inflexible. I've tried I think all possible installation sequences, and I just can't get all 3 in and connected. So, I'm looking for successful strategies. I haven't tried removing any of the myriad things in my way yet. I thought I'd check here first. Also, it gives my back a rest.

I understand there are multiple wiper configurations. Mine is just a single wiper connected directly to the motor thru the cowl, with the motor connected to the switch with a bent wire that hooks thru a grommet on the switch arm and pokes thru a grommet on the motor arm.
Picture attached.

This was all connected before I removed it all, though not actually working.

Thanks,
Steve
