How to do it? Got an engine and a gearbox, like the title suggests, that I want to sell. Going to stick them on ebay. Collection only? Rules out a lot of buyers. They are heavy. Royal mail will say fk off! Any couriers or delivery firms recommended?
If the engine and gearbox are the kind of thing a modifier, kit car enthusiast or similar would want then they will likely be up for collecting from you anyway.
In the past I have had some epic Road trips collecting engines and sheds for various projects.
As said above, a pallet is the way. Cost 40-50 quid. Get hold of a pallet from a skip or wherever, buy some pallet wrap (saran wrap) from ebay for a couple of quid, and job's the proverbial good 'un.
