hiya,
when i converted my commercial 3 door into having a full interior, i looked into all of this , as one breaker had a nice set of front seats but they were both passenger seats, but didnt do it as the seat belts brackets, and the lever to put the seats forward were all on the wrong side, and without taking the seat covers off wouldnt know if indeed the bolts were behind the covers etc , but i expect youve looked into that
hope im not telling u how to suck eggs but have u thought about seat covers etc until a suitable seat comes up,
not sure also if they have the same frames or indeed if they are angled differently
as also if u tried to swap over sides the covers would also be wrong, having to making a hole etc, or taking the covers off both seats in order to try and match them up,
could u do a swap on ebay etc,
hope u didnt mind me suggesting it but seems abit of a nightmare with what your trying to achieve at the end of the day etc and hope that doesnt come across as disrespectful
gary
