Throttle cable/pedal help!

Had a search and mentioned this in the other throttle thread but thought I'd get direct.

Set off in Mk1 LT35 on Saturday, pulled out the top of our road and the go pedal dropped to the floor. Managed to get it in a parking space on momentum and had to abandon it as we were rushing to a wedding. Not being technical I guessed the cable had gone, but so say it may just be a bit of linkage.

I could pay for a recovery to a garage and pay someone to sort it, but would rather not, especially if it's a matter of hooking summat back together or replacing a spring. The pedal is pretty knackered as it is so that may just be a replacement job anyway now something's given up, but should I want to have a nosey how do I go about finding out what's wrong?

I'm pretty clueless when it comes to things with engines but I'm handy with push bikes and got a brain and hands, and some tools. Where do I start?

Edit: well in part I can do a less rubbish job of the search function, having a poke through some other threads now

Cheers MLT.
Had a poke around this evening when I finally had a moment:

Looked underneath and no sign anything was amiss. Gave all the cable run a tug, seemed secure, squeezed the bellows and could feel the cable inside.
Then started from the top, screws fixing the bearing cover were in a horrible state, faffed about for ages and finally got the last one out with some mole grips. No obvious problems except no sign of any pressure spring! Looked simply that the push rod had fallen out of the hole in the bottom of the pedal. Is that what the pressure spring is supposed to prevent?
In the absence of one how can I go about fixing that problem?
Also the pedal was already having problem slipping off the bearing pin at its bottom edge, any ideas?

Need to get some new screws to fix the bearing cover back on, and solve the problem of stopping the pedal falling off again in future.

Crossed the line of getting involved in the van and suddenly there's a mental list of jobs. Had to pull up the sodden mat/sound proofing, which has made me think about getting on the case plugging up wherever the rain pours into the footwell (I gather I'm not alone with that issue!), and then there's the rest of the bodywork problems...

Pfft, loss of power at four mph on a residential road - didn't feel particularly risky!
I reckon the spring is long gone, I gave the cab a big sweep of all the surface debris and crud not long ago...

Is the pressure spring just for holding the pedal on?
Surely there's an easy bodge solution for that.
Similarly what's the need for official VW screws?
I'm sure I can find some that fit in the hardware shop up the road.

Oh definitely it was the right place for something to break, apart from on the forecourt of an LT expert.
I'd have thought I can match the screws, but perhaps not.
Not clear to me where the spring actually fits or what it does! Th exploded diagram seems to show it goes on the other end of the push rod but I can't see what it's doing there. If I get a spring will yer average mechanic know what to do with it?

Man, that spring is tiny.
Here's how it looks on mineif that helps any ...

Great, that definitely helps. Loads of them listed on eBay, should be able to get one easy

Beastyvan will be back in action in no time!

Going to need to replace the pedal I reckon - thought there was a link here to someone selling a kit but can't spot it... 
Also looking at the pics posted looks to be a cap on the end of the push rod with some sort of locking ring on - definitely nothing like that on mine, perhaps this is why the pressure spring won't stay put!
Wondering whether I'll go and source a new pedal set-up and then find that it won't stay on the rod either.
