Upto '71, bays didn't have the gearbox cradle either, so i wouldn't think it would make the van unsafe to remove the valance, just less safe. VW did quite a bit of beefing up of the rear end from '72 onwards, and the front of course. It's more that removable valance conversions always look like they've been done with a tin opener. I reckon i could get a t1 engine out in 15-20 mins if it wasn't for the nut behind the fan housing, that always adds 10 mins.
Hey Jeremy, my panel van has a removable rear valance, hasn't caused any problems at all... i'll upload some pics shortly
The remove able rear valance won't save any time, as you will have to take the rear bumper off and the valance, in that time you could have half the engine disconnected
Wow, I really have opened a can of worms here, I was only looking on saving £150 on buying inner and outer valance by making my own! Running a T4 lump so nice to know its easy to remove thanks for the input
