[rona wagon]

Hi all, i'm doing a 1g in to corona wagon (st141) 1g- w5x box. Do i have to mod the tail sharft? and witch diff should i run?

no you don't have to modify your tailshaft.

get a IRS RT142 end and i think you can put a ma61 lsd in there

um no that would require too much work, live axle -> IRS
would be cool though...

although i think you should get a w55 at least, corona wagon's only have a w50 (a little weak). you still don't have to modify the tailshaft.

did the ma61's not have the IRS??!?!?!?!

yeah.........

ST141 Corona = live axle = no IRS diff swaps. You'll definitely need to do a diff conversion but I don't think there are any direct swaps, at least nothing strong enough for a 1G.

As for the tailshaft, if the car originally came with a Borg Warner transmission then yes you'll need a new tailshaft. If it originally came with a W5x box then no you won't need a new tailshaft.

four speed manual box behind 2s (box?) but the 1g and box 5 speed standerd (w5x?) IRS would be good but personaly not a fan!

if it's four speed then it's borg warner, 1g comes with w58

So i guess ther's diffrent taile sharfts for auto,manual (4&5speeds)
