Might be able to bounce some ideas off you.
How did you go about offering the cage up?
Rear first, but did you put it in place with wheels on to line up in arches? then draw in the holes to drill through ready for the bolts?
bolt and bond the rear, then fit the front cage?
That's my plan anyway.
What did you do for reverse? I have got a mahooosive starter motor and an even bigger sprocket to gear it down. Sound good?

If you get the front legs of the cage right into the front corners and then mark across the floor taking a reference point each side of the car to make sure it is square. Dont bother about the wheels in the arches as this can be adjusted anyway on the rose joints. If everything is straight then there will be no problems. You have to make sure that the rear uprights are vertical (measure distance from the back of the B pillar at each side and top and bottom) before you mark it out. The cage tends to tip back a little due to the weight so you have to get it to just right angle before bolting it up. This tilting can make quite a difference to the base position of the rear cage. I had the back of the car attached to a winch so i could raise and lower it easily whilst the cage remained stationary, to get the correct angle.
One thing that i found with mine was that the cage fit was very tight at the back (width across the floor) the first few times. But, eventually the shell seemed to stretch a little so that a small gap was present at the side of the rear leg plates (about 1/8"-1/4"). The floor is also quite 'floppy' at this stage, so i bought another box section from Somerford minis and welded it across the floor. Also, the seats sit straight across the box sections, so quite easy to fit. Only problem was the handbrake cable mechanism, so i had to cut the box section in half! Anyway, that made the floor about 10 times stiffer!!
Where abouts do you live?? Would be interested in seeing it!!
Mine has no reverse, far too heavy for me!! :wink: :wink: But probably a good idea for a road car!
Last weigh in was 460Kg, quite light i think??? However, i think 400Kg is quite achievable in the future. The car absolutely flies, so no problems with power. It will even pull and accelerate to overtake from 2000rpm in 6th gear!!

because I reckon the floor is a bit floppy too.
