It just so happens that the Laycock GKN LH overdrive (has fitted to the MGB) is the most easily sourced overdrive unit available - its also the strongest whilst also being the cheapest to rebuild when compared to other units in the market This is a overdrive conversion being tested on a lathe bed - the red sections to the rear of the box being the overdrive adaptor housing (owner / engineer fabricated and not a off the shelf part) and the overdrive these take up the same length in space has the removed tailshaft from the original Jowett box - hence there is no requirement to modify the propshaft and the car can be returned to original specification if required by simply bolting a standard Jowett gearbox back in Jowett Jupiter - they are great cars but the little 1500cc boxer engine starts to scream at 65 MPH - the solution is to fit a overdrive and it makes for much better cruising speeds So a brief hijack of Sam's 'V8 B' thread - why do I need MGB overdrive gearboxes when I don't own a B ? - well I don't need the boxes either but I do need the overdrives - you see I have a few of these to restore / rebuild over the next few years (I think I am up to 4 number currently)
