Blimey, I like the look of that buggy! well I would wouldnt I !!! ;D
Its looking good Mick, You need to start making dummys of all the parts you need to fit in the buggy now, then you can make sure, as I did that all the parts will fit!
Also check the gear change on that engine I bet its a rod change not a cable in which case youll need to make a cable change adaptor similar to mine to shift gears, I used an MR2 gear change unit and then custom built (dont I always)
Keep up the good work! lets see more design photos ;D
