Is it just me or do others believe we have lost the general era of good customer support?
Example. I'm trying to replace some rowlock crutches and (top mount) sockets on an old but unused ('as new') fibreglass pram dinghy I'm trying to sell on behalf of my Mum (it was Dads).
Now, the nylon rowlocks weren't kept with the dinghy and whilst we have a small container full of them, most are also quite old and even if not exposed to sunlight, they tend to become brittle with time and I feel replacing them on this dinghy would be a 'good thing' (for the sale and new owners especially).
There are no identifying marks on the existing sockets (that I have found so far) and from measuring them, seem to come from an imperial era as the numbers seem to come out best in inches. Eg, the OD of the tube is 1", the ID (for the rowlock stem) 3/4", the distance between mounting hole centres is 2-1/4" etc.
So, I've Googled quite a bit and none of the offerings from the usual suspects (Holt, Allen, RWO, Plastimo etc) seem to have anything that is directly compatible and that means any replacement may require screw holes filling and re making etc. Worse, I think quite a bit of support for the socket is provided by a reasonable fit between the socket and the gunwale and so if it's not a 1" socket (they are typically smaller ) I may need to 3D print / turn suitable bushes etc?
Now, the frustration is trying to get accurate and complete dimensions for any of these things. Some sites give you some dims but it's rare to find all. Now wouldn't you think that if selling something like this that is an 'engineering' type thing, the complete engineering drawing with all the key measurements would be right there beside the picture and price?
So, do I have to order one of each of the possible candidates to either measure them myself and then send back what I don't use, as most of the emails I've sent (politely) asking for such dimensions have either missed the point or not got a reply or push the suppliers to do the sensible thing and offer these items for sale with some supporting dimensions?
Is this how the world is now, no "I'll go and measure one now, email you the result and update the website, sorry for the inconvenience sir."?

 What complicates matters is that you then also need to find a compatible rowlock crutch with a big enough jaw to allow you to get the oar shaft in but an ID small enough to be a good fit on the sleeve.
