I don't know how extensive we might be able to make this... but I propose to start off like this :

Anyone that has any old bad injectors out of a 616 or 617 send them to me... I will weld up several examples of them which can be used with a slide hammer or something close to that.... actual hammers are too heavy to ship around.... ' homemade' articles can be used for that end of the tool....

Someone else could volunteer to keep the records of who has them and notifies them when someone else needs them.....

Or they could be kept by someone and sent to those who need to use them..

Anyone needing my mailing address for this email or PM me....

Any other suggestions or comments ?
