2nd won't engage?

[PeteVS]

A few years ago, I put together a "39" trans with what I thought were all the right parts. Later synchros, later shifter top and a 29 tooth cluster, 15 tooth input shaft. Yesterday, I got everything together, engine running and I tried driving up the street. First gear- it's all right! Third gear- it's all right! Reverse gear- it's all right! SECOND GEAR- NUTHIN!!
I took the top off today. The center of the groove on the synchro wants to be about a 1/2" ahead of the center bolt hole for the top. With the shifter lever in second, the center of the fork only goes back to about 3/4" ahead of that center bolt.
It's hard to read the part number on the shifter fork but it appears to be 68-7230. Is that right? Could the shifter rail have the hole in the wrong place?

I have to figure out how to load two more pictures...
