318isPMK It doesnt sound arsey good question really , Brian and speedtouch have got it really ,the lad doing the build is a friend of mine and was looking for a donor car ,my old e30 cab was just sitting there .It was very solid with zero rust and already had a m50 engine in . the Jag shell was just that, i think the guy got that cheap anyway as it was just a bare shell with just some other odd and ends with it .It was decided the e30 would work because of being a cab it would have a strong chassis and it turns out it was very strong just about perfectly matched the Jag wheel base (that was just luck really),but yes front engine rear wheel drive ,disks all round ,parts are cheap upgrades are readily available he got the e30 for £650 so even all the bits he doesn't use he will make alot of his money back.
in the later pics when the e30 was stripped down to bare bones it sat 4" higher then when it went in thats how much weight has gone.
I will be going down to see him again in the next few days im very curious to see what he is going to do in the sill area as it doesnt look right in the pics this is the latest one i have seen from him .

see what i mean with the sills i am sure he will sort something that looks right just not sure what yet
Thanks for all the interest too
