Spotted in the local free FB for-sale pages, paid £25 from a local seller. Gave it a bit of a clean, some handy grey 'smoothrite' over minor rusty patches and put it all back together with lots of copper-ease on the joints and nuts etc.
Tried my dual band feed and thought it would be a good idea to see where it was looking at the dish, so using the handy afternoon sun, I took the attached image. Not exactly a 'pinhole' camera but it was easy to adjust the dish so the sum was clearly central . Its an offset dish so its not aiming at the centre. The LNB arm is braced and not adjustable so I'm assuming its 'good to go'.
Also shown is how the patch assembly will sit, which I think looks about right. I couldn't move it backwards much more unless I cut a bit out of the reflector (probably not a good idea and probably not needed?). Hope to put it up tomorrow and try my feed (on rx only), see how it compares with the existing 1.1x1.05, a TRIAX wobbly special.
BTW, if anyone wants the spacer collars (shown in RED) I can print them too and they just fit into the post office £1.06 size. OD 39.3 ID 21.9 22mm long, two split halves.

Some time ago I was trying to make something universal, and that something could be attached to round or square bottom-feedarm. Came to this solution:
Side holders can be removed (you do not need multifeed), but what is left can be attached to feedarm you have. Perhaps the feedarm could be shortened little bit. Maybe it is possible to reconnect sidearms little bit closer to the dish, so bottom feedarm will go little bit down.

Thanks for the images, they speak a 1,000 words
There is some adjustment in the bottom arm fixing so if I moved the support arms that would be possible. I'll see how my RX MER compares tomorrow.

Gareth!
I think you can try something like this
I think it is better to cut off piece of original bottom feedarm, drill couple of 6.5mm holes in it's bottom part. Then connect piece of metal (as on the picture) and bend it at needed angle.
