changing down with a PPG kit
ok ive got the hang of changing up the gears, just double the clutch it driving at normal road speed and just hammer it in if im wragging her!
but for the life of me i cant get her to change down without it crunching unless i really let the speed drop right down...
anyone experience this or is it just me?

I think it's a dog box david.
Essentially you need to be very positive with the gearstick, the slower you try and shift, the worse it will be. The more gentle you are, the more damage you do, I cannot overstate this.
The easy way to do it is change like a normal gearbox, but as you put it into the next gear, that movement needs to be quick and positive. This is not the same as being a ham fisted gorilla mind you! You will find with this method that you get a "clunk" with each gearchange, and also remember you don't need to rush to get it out of gear.
The long way to change down, is "double declutching" and please note this is not "heeling and toeing" although the two techniques can be combined. To double declutch your gearchange sequence becomes:
1: clutch (full press)
2: change out of gear, and into neutral
3: declutch (fully lift)
4: clutch
5: quickly put into next gear
If you do it properly, you will have a silent gearchange with no feedback through the gearstick, you if you're changing down from high RPM, an additional blip of the throttle can help during step 3, while the box is in neutral and the clutch pedal is up. however if you're changeing at low RPM while driving sedately, you don't really need to do this. Beware waiting too long between steps 4 and 5, otherwise the speed matching will have been lost and you'll have a crunch.
You can also double declutch UP the box, but here you defintely don't blip the throttle between the changes, and you can afford to do it slower as you're waiting for the box to slow down rather than speed up.
Hope this helps

If you get the balance of revs right, it is just as easy to change gear without the clutch.
Otherwise exactly as Paul says.

it sounds like hard work, but with practice either technique becomes second nature. I would say the most damage the box will ever see has already been done. You need to remember the dog box, when my car was civilised it was easy to forget, and change gear nice and sloooooowkkkkkkkrrrrunch!

3a: rev blip to speed match
4: clutch
5: quickly put into next gear
6: decluth again
Otherwise you will be declutching and clutching (as you put it) with no action in between!
It can be speeded up by taking it out of gear as you lift off prior to the downshift, momentarily there is no load on the dogs and it will slip out of gear if you already have the pressure on the lever, if you get the rev match right you can also put it into gear with the clutch up, but that takes a lot more practice (about 400 miles over Christmas when your Ford's clutch cable snaps on Christmas eve helps mind! Had another chance to brush up on the Scoob when the pull release bearing pulled - right out!)
