I've bought several seats from kdrseating.com nice people to deal with and often have good deals on eBay 

Look up KAB P2 seats on that auction site, lots of wheel horses used that model seat and we’ve always got them at a reasonable price. 

it was marketing, before 74 they were 6 speed (with 2 reverse) after that they became 8 speed (inc 2 reverse)

So, this seems to be becoming quite a big job this thing!
 
I have milky (but not brown) gearbox fluid, a bad shift boot that needs replacing, in low ratio it will happily shift 1 way between 2 gears and not the other and I have horizontal movement on the axle on the left hand side.
 
I think I'm looking at shift boot, seals, bearings and maybe a worn gear from shifting on the move?
It's got the larger axle.
 
Where can I get these parts in the UK and is it a diy job?
 
Thanks for any help!

Just spent the weekend at Ardingly, arrived Friday afternoon in lovely sunshine. Saturday started well until lunchtime then the rain spoiled the rest of the day then on Sunday it was bright and sunny which brought in the public and it was packed, in all a very enjoyable show.
Heres a few photos.

Going to take look at the hardwear i have left on the bonnet Monday, I was too busy looking at the exhaust and points today lol. 

Ours was the same, unfortunately i cant find a photo but the round ones were the same 4 1/2" diameter as the originals so fit perfectly and were extremely bright, the square ones will work awesome too! 

I just have the square holes in the hood and think I will use led like you have. You can get sealed 3x3 and 4x4 cree work lamps that will do the job, I would give them a light tint to make then less terminator lol

Do you need the round lamp type bulbs? I managed to source some a few years ago for my Cub Cadet but they are very hard to find. On our C-125 we chose to use round LED lamps and made a bracket which bolted to the hood.

So after seeing meetens recommended on here (thanks!) I just called about a filter and cover for my k341.
Paul answered and found the part number then gave me the outrageous rrp!
2 minutes later he's given me a fantastic price filter and all and I've given him my card. 
They have a new customer for sure!
Very highly recommended 

I've used Meetens a few times and found Paul very helpful.
