[Richard Coutts-Smith]

Thanks David, I will go with the black Jack & Handle parts, same for the wheel nut tool/Tommy Bar and green for the starting handle. Black will make a change from all that green.

Rick, thanks for the reply, I do have all that info, what I don't have is any idea of what the bits look like, or the method they are used. However, I think I have been looking at it the wrong way. I assumed the battery was held down with a bracket on top, but assuming that the battery used was one of those aluminium cased jobbies, there was possibly a hold down point on the bottom which locked into the countersunk block with the parts on the list. (For the record, these blocks are not threaded UNF, but UNC.) If this is so, I will have to do a mod for modern batteries.
Regards
Rich.
