It depends on which trans you have in there first. My wife's Fastback (before
it got converted to AT) had a bad 1st and reverse in it when I bought it back
in 1989. I used a later single side cover bug trans to replace the OE
trans.The OE trans had 4.12:1 final gearing, while the replacement had 3.88:1. I
noticed that the engine didn't seem to turn as high a RPM as it did with the old
trans, but it was a little harder to get it going (but nothing compared to 2nd
gear take offs). The swing axles used different gearing than the IRS cars did.
I believe it was 4.25: or 4.37:1. Or these were the different gearings
between a bug and a t-3.

I don't think it would be that bad, since up to 73 they used the same final
drive ratio.

Not necessarily.

Like I mentioned earlier, I've been using a later bug trans in my t-3 since
1991. If anything, I think it gives me slightly better fuel economy. : ) If
using a bug trans though, keep the t-3 hockey stick and nose cone. This way you
don't have to chase down a front trans mount for a different car. I hope this
helps.
