not to hot on that gen of corona's...
but...
the slightly newer ones (74ish +) share the same suspension setup as the hilux. and the control arms/spindels/ tie rod assy are interchangeable for rona's and hilux's up to early 78, then the rona went to struts.
so id be willing to bet it has the same suspension under it as a 71-72 hilux, and that is confirmed the same as the later lux's up to 78.
the only real problem i see is replacement axl's (rears for those not paying attention) i dont think any newer leaf sprung axl is a bolt on, cept maybe a te51 (79)or earlier corolla. so you would have to make new spring perches, but on a high note, it should be VERY easy to swap to a 5 lug and get a practicly indestructable 8in diff.
then if the motor n tranny go, slap a 2xR in there with a W58.
if you damage body parts, your pretty much F'd. there used to be a guy on here (
http://www.turbocreations.com/corona/ ) that horded early corona's and sold through that site, not sure if he's still around or not.
good luck, post pics, and drive the piss out of it, i do
