blue 202 into lj conversion

hello i know there was a post ages ago similar to this
i am fitting a blue commodore 202 into the lj soon hopefully within a few weeks/months (as the reds on its way out)
to the point i have a aussie 4 speed box in the lj at the moment behind the red 202 i was wondering if theres any specail mods or anything big to get this behind the blue 202 or is it the same and requires nothing ??

also something about hammering down the dam in the lj sump??

also if there was any mods to do for this conversion

radiator ??

im also planning to convert the blue over to the commodore efi (when i can get a surge tank / efi pump)

anyone have any ideas what a commodore one costs 2nd hand and brnad new ?
