Toploader gearbox overhaul

[KevinW]

Toploaders are rare in the UK, but very common in the USA.
Take a look on the Sunbeam Tiger forums, as the V8 versions used a toploader. You should find some leads there.

Anyone know who or where can do a good job of overhauling a toploader gearbox?

My local garage has a RAM cobra with a stroked 390FE and toploader. The first and second gears are slipping and jumping out so needs repair/overhaul.

Near Leicester if there are options.

Thanks.
