Yes well I wish I could do it for my corvette 2 base,but it's buggered on the top as well.Welding won't help.However the newer base for my Cortina 2 should be easier to repair.I took it to Baxter engineering on Gladstone St in Fyswick.The last job I had we got them to do some work on the trucks there.So I seen how good there work was.So that's why I took them there.As you can see [Censored] good.You know how on say the model 5's the edge wears down.Well on this base we did an experiment.Which by the look of it will work.So even if they are worn on the side I can fix it so they will be round again.Clever I am.Just ask me.Which really means F.I.G.J.A.M.
