Well i just fitted this as Si has mentioned its fairly straight forward to install.

As you now most ford bolt patterns on fwd boxs are the same and the st170 box is no exception. The only area i would not be sure on for the cvh block would be the rear posistion starter...

Has anyone fitted a mtx box with this does the block allow that... thats the only area i would check!!! zetecs are fine.

As for fitting- fabricate a mount and she fits with loads of room, much narrower than any other box but its a little bulkier so i have had to loose the brake servo and master cylinder.
bias box is used now which solves the hydrulic clutch issue.

Si has used and abused his like he says and i believe on strip down recently no signs of wear at all....quiafe diff needs to be added.

Ive yet to test mine but will be throwing 450 through it so will let you know.

Also you can get uprated parts for these now like uprated poly mounts etc.

You have to run a st170 compatible clutch/fly
