the early P1s without the bias valve has small rear brakes from what I have seen (I could be wrong).
If you have the larger rear drums it may well cause you problems. I don't think there is any relationship between having abs and having one or not, the confusion comes in because the later cars (P3) had a better version of the ABS with EBD which replaced the bias valve.
I would be very wary of removing it, try and free it up or see if you can get one. Although I appreciate how difficult either of those is going to be!
