As mentioned previously, after I found that Eagleday.com stocked AMP 'Junior Timer' connectors and parts I placed an order for some pins, a few replacment boots, and some of the retaining clips.
The package has arrived today (week after it was shipped), and I'm impressed! Unless I find a better source, I'll be ordering more of the AMP parts in coming months so I can start replacing a lot of old connectors and bring the engine-bay electricals back up to scratch in my 900's.
I'll capture a pic of what I bought and put it online in the forum threads where I'd also mentioned Eagleday for those who aren't sure what I've purchased from them.
Regards,
Craig.
