shame u not own south i got full set of rear seats takeing space in my shed, probelry the seat belts to

Hi singledad, I am looking for some rear seats. where down south are you? and how much would you want for them?

im in west sussex near worthing,dont want alot for them just seems daft to have them sitting there if someone can use them for the price of a drink

10w40 suits our climate best. the numbers are rating viscosity of oil(thickness) at high and low temp. me myself would only put mineral oil in as synthetic can give old rubber a hard time. mind you its very difficult to find nowadays.

the book says fully synthetic but I run on Semi and change it regulary
