the only mount you get is the one that bolts to the gearbox. you need to make your own crossmember for the box. use some 50x6mm steel and use sandwich plates to hold it through the floor.

For photos and information, see Datsun1200.com Tech Wiki: Toyota 5-speed

After reading this I dont know why anyone would pay near to or over a grand for a 56 or 60 series 5speed.
Anyone know what Dellow are charging for both the kit alone and the kit with reco gbox these days?
Anyone got one for sale for that matter?
(hell Id have more luck asking that than for a 5 speed 56 or 60 wouldnt I?)

Here are two reasons to use a Nissan box instead of Toyota box:

1. 56-five speed has five driving gears. Toyo box has 4+overdrive

2. Keep it real, keep it all Nissan
