dunno id ask a mechanic then... and youd have to worry about insurance too, as long as they will insure you even though you have make shift subframes I guess your ok.
macro rocks btw
what the alfa romeo GTV ones??
you should have spoken sooner, I sold the pair for £27 no complaints as it was £12 more then I payed! got a set of Fiat coupe front seats in now that I picked up on ebay for £1 lol had to go to bradford to collect though.
