What car did the 23mm master cylinder that will bolt into our cars come out of?

I think the 914/6's came with the I-beam type front end support if I remember correctly?

not sure what you mean by the I-beam support, but i did recheck the ETKA and sure enough /4's do carry a different part number for the rear crossmember - i always thought they were the same. 6's get a '901' number and 4's get a '914' number and you can't see diddly squat on the picture, and there's only one and you can't tell which it is anyway...

and i don't have a /4 crossmember to compare... i do recall having to re-twist / re-route the reservoir lines but it was ok with the stock parts in different places.

the aluminum crossmember arrived in "around" 1972 for the 911, "officially" for the 1973 911RS, but not all RS's got them, and not all "regular" 911's didn't. opinions vary as to why. almost certainly the first 500 homologation cars got them at first (lighter) and at least a few of those were refitted as roadgoing cars with heavier stuff. certainly some of the competition cars got the steel members (stiffer)... as for the rest - it was probably whatever was available in the parts bin that day, in the absence of a special order...

looks like my '71 911 carries the same part number as the 914.6 so barring pedal box dimensional differences i may be good to go!

thanks ! i learned something today !
