What is that thing you always forget to order

Just doing an online parts order (oil filter etc) and always remember too late to add that other thing I was going to buy.

What is it that you always forget to include?

can't remember...

for a service, sump washer....

other stuff usually a gasket or summat.

Done a few rebuilds and always forget things, Usually something that I need before everything else anorl

Last time wasn't forgetting to order the parts, But ordering the wrong ones.
Ordered late swivel seal retainers not realising they was different to the early ones :doh: So that stopped me building the front axle up.

gaskets n' washers - im not too bad tho

chips to go with my kebab

Best idea so far is the sump washer.

The tab lock-washer for wheel bearings .. and have to hammer the old one flat ..

I write a list which I keep adding to as I go along. When I think I have reached the shipping limit or I then need something urgent I then place my order.
