Thanks for the Feedback.
No Meteor in this one I have a G29T German flathead in it, with swedish made Elco Twin replica heads, and Lucas Dizzy in the front and Bosch in the rear.
What im trying to do is to convert my open drive truck gearbox, to closed drive.
Using this home made "Lincoln gears" set.
I opened up two 42-48 gearboxes, to pic parts from.
One have the spring an ball synchronizer type.
And the other have the other type, that according to the interwebb is the best type.
So i guess i will use that one with my modified NOS sync rings.
I have left the syncro rings on the left to my local machinist to open up the three gaps.
So it will be like the one on the right
I think that will work OK.
Will let you know how it goes ;-)
