Classic Style

I'm lookin at buyin a '79 930 stock tranny to replace my '74 915, but I wanted to know what the factory ratios are? I've got an LS1 backed up to my 915, and I'm runnin a little high on the Rs for freeway crusing (3k at 70-75 - broke the speedo cable). I guess really the most important thing is that 4th gear is taller than my current 5th by quite a bit. Any info is much appreciated

Thanks!
