ta22 pedal box does not bolt in.
if you look up johnny rochester on this site or just google his name you will find that you will need to modify the crossmember to use the standard steel engine mounts.
ta22 rubber mounts fit fine.
ive put ra40 struts into my ke35 with the lower spring mounts cut off and the ke35 ones welded on, the strut tops are standard corolla.
use you ke pedal box and modify it to except a hydraulic system.
a ta22 pedal box does come in handy for this though.
ive also put a ta23 T series diff into the rear. only drums but hey. better than the stock tooth pic.
hope this helps.
also old rolla bloke knows his shit.
peace
