Three on the tree options

I have the A903 in Vixen and I can get it in 1st long before I roll to a stop with no grinding. Same with the T18 4 speed in my Ford truck. It's also non synchronized 1st gear. I guess it all depends on what you're used to. Now the truck I have to wait until I'm going a little slower than the Valiant, because it had a 3.73 rear gear and spins the transmission pretty good, but It gets in there still rolling.
