I'm after either a Type 9 gearbox or overdrive gearbox for my German mk2.
Before I go buy anything just wanna check a few things:
Type 9: If I have the box and gearstick is it a straight swap. Will the existing 4sp cross member be OK or do I need the type 9 cross member? Do I need anything else? Prop flange or anything like that.
If it has a Diesel Bellhousing will the bellhousing off my 4sp fit?
With my stupid 5.83 (I think) diff how much of a difference will the extra gear make to my top speed and revs at motorway speeds? Currently 50 is about top speed and it's revving at I'm guessing nearly 4500rpm.
Overdrive setup: I know I need the Overdrive gearbox and unit, prop, gearstick and crossmember, but do I need anything else?
Again if it has a Diesel bellhousing will my 4sp bellhousing fit?
And as above what difference will it make to my top speed and revs at motorway speeds with my stupidly geared rear axle?
Which option overall is most reliable and which gives the best gearing? I've read Overdrive units can overheat with low geared axles?
And finally does a LWB prop split in half (ie is the slider in the middle?) so I could fit it in the car if I do get lucky and get an Overdrive kit?

i dont have enough experience with overdrive units to tell you too much but i have fitted a type 9 to my mk2 for a while when it ran a pinto, before i converted it to turbo di. the original prop will fit straight in and the 4spd x member should work with a re drill and bit of spacing on the mount at most. the diesel bellhousing will bolt up to the adapter plate currently on the back of your pinto. personally id be looking at swapping in a 4.63 axle if i could get hold of one as i think you will still have no great comfort even with the 5spd fitted. heres a link to a thread i had on the other site at the time and ive just noticed you actually commented on it, lol!! couple of pics on page 2 which may be of some help. fordtransit.org/forum/viewtopic.php?f=27&t=47237&hilit=few+jobs+on+my&start=15

Thanks. It would be nice to find a mk2 4.63 back axle but they seem to be rarer than Overdrive units.

Also if I got an Overdrive setup from a lwb mk3, will the prop fit my mk2 OK?

Make sure the overdrive box is for a 4 cylinder petrol, the diesel and V6 has a longer input shaft.

Dont forget this is for a mk2 2.0 Pinto, I thought they already used the long input shaft? It was only the V4 that used the short input shaft
The one I've found is from a Diesel. I was told all the gearboxes were the same, it's the bellhousing that's different and to fit it to my Pinto I need the adaptor plate and bellhousing from a Type G gearbox? (If I can find one!)

Im not 100% sure but i have been told the V6 has a longer input shaft. I think a 4 speed & overdrive still won't give enough increase in gearing to make it worth while your really need a 4.63 diff.

I've got an overdrive kit off a mk3 for my mk2, loom, prop, erc, I've been told it fits straight on my mk2 just got to swap the bellhousing over. AFAIK all the Overdrive gearboxes are exactly the same.

Thanks Ralph its for my Minibus so i've already got the 4.63 diff - one just turned up locally but that was fitted to a V6 previously, do you have an overdrive crossmember amongst you stocks by any chance? I've got an overdrive kit off a mk3 for my mk2, loom, prop, erc, I've been told it fits straight on my mk2 just got to swap the bellhousing over. AFAIK all the Overdrive gearboxes are exactly the same. Harry do you know what engine yours was fitted up to originally? Any chance you can measure up the input shaft?

I havn't a overdrive cross member but i think i might know where i can find one. Wouldn't you be better with a type 9?

I'm hoping at some point to put more power than standard through it so I don't want to take the risk of a type 9 + the car ones are getting silly expensive now

The best and easiest way is a 4.6 axle or diff.

An overdrive gives approximately a 20% decrease in revs at the wheels over a standard 4sp transit gearbox. Ratio wise AFAIK there isn't much in it between an overdrive gearbox and a 4.63 rear axle to top end. Best combination is the Overdrive and 4.63 back axle.

Already got the 4.63 back axle fitted, just want to make it less busy on the motorway, Harry is there any chance you can measure the length of your input shaft on your o/d box please?
