MGBGTV8 gearbox with overdrive Tony Head, says "fellow members might be interested in the V8 gearbox and overdrive for sale on eBay for £250 with collection from Newport in Wales. Looks in very reasonable condition from the photographs, which include views of the vital layshaft and reverse shaft support post. Seller claims he can send video of the box internals being tuned over by hand. I would probably buy it myself except I already have a spare box stored in the garage “just in case”!" Posted: 181212
