there is one at a yard here In kentucky I think they want 60 for it. Id charge you like 40 to go pull and about 90 to pack and ship. I think it has around 150k miles on it.

[SR Heer]

does it have the bolt type tranny studs that allow it to be installed in a Mk1 trans mount system?

[SR Heer]

I am interested - yes - does it have 90 or 100mm flanges - do you know what VW it is in?

[bbob203]

90mm I beleive 88? golf gasser.

90mm I beleive 88? golf gasser.

all the ACN/AON/ASF/ACL trannies were 90mm..

if you want it to have 100mm cups, you gotta swap them on..

its not hard..

[SR Heer]

Ok - thanks this is going into a Rabbit Pickup and once I swap them over to 100mm flanges I want to use the 80% Peloquin shim kit but what CV axles would I need to order - like for what year and make VW to fit 81 Mk1?

The ACN at JY needs to have the studded bolts or at least the treads for the studded bolts for tranny mount so I can put into Caddy - please check - thanks

[bbob203]

Are you talking about the three studs on the firewall side of the case where the ring and pinion is inside of? The asf i just put in my car has these so im guessing this one will too.

[SR Heer]

I am thinking so - this is what they tell me - I will have to look to see if those are the ones that are used for tranny mount in Mk1 application

if not installed... you can install them or use bolts...

keep the 90mm stock axles with 90mm flanges...

else 100mm flanges... set of 16v rocco axles and you still gotta clearance the hub or cv joint to fit... not so simple a swap... and costly as mk1 100mm axles are 16v rocco and a few cabbies after 89 had them... and mk2/mk3 are too long to fit...

[SR Heer]

I was wanting to use the 80% LSD Peloquin shim kit - which is really only applicable with the 100mm flanges - so I can change out flanges and or find a Rocco ACN with them allready in - now as far as 100mm CV axles that will fit in a Mk1 - exactly what years and what cars was I to look for in Sciroccos - and then the later year after 89 Cabbys correct? Do you have or can you get any CV axle part numbers or directly point me in the right direction? Now you say there is still some clearnce issues with the Rocco 100mm to fit in? How would I adapt or what would I need to do to make them to fit?  Thanks for all the info!!

[CRSMP5]

as pm said.. later 90mm joints same as 100mm except bigger diameter and deeper cup.. both are spring loaded and can swap out with ease...

[bbob203]

go read thread on 80% kit in upgrade section.

Broke has a picture on his site; of an ACN trany that didn't have the holes for the rear motor mount studs,.. so in rare cases some did not have them.

[SR Heer]

thanks - read thread -
Whats saying that since the 100mm shafts are a bit shorter - how much I know not but the concept is this - that one could put 90mm joints on 100mm shafts to come up with enough clearance to install an 80% shim kit thereon and use with 90mm flanges - so actually maybe the 90mm flanges with 80% shim kits would work best if hooked onto 100mm CV shafts with 90mm joints installed thereon??? Does anyone know the difference in length between the 90 and 100mm CV axle shafts???
