Hi,
I'm putting Rover Metro seats into a mini. The rest of the car needs certing (brakes, suspension, engine), so I thought I'd get value for money and change the seats.
The Rover Metro seats have 'legs' or tabs that stick down at various angles to meet the original bodyshell. I need the rear ones to 'mate' to the more or less flat floor of the mini.
Which is best:
1. Cutting off the legs and welding the seat runners to a basic but appropriately robust subframe and bolting that through the floor as per the specs (spreader plates, 12mm grade 8 bolts etc), or
2. Making a subframe which bolts to the floor (as above), but bolts to the existing legs? This means effectively the seats bolt to a subframe and the subframe bolts to the floor.
I appreciate I may need to provide examples of welding to convince the local cert guy that I can get sufficient penetration (phnaar phnaar...) etc. Option 1 is my preference as it lets me get the seats as low down and back in the car as possible since headroom and legroom is at a premium and will be 'cleaner' in terms of design and execution.
That's the back of the seats. For the front, the easiest method I've thought of would be to bolt the existing front legs from the runners through the crossmember, as in the original mini seats, except they use 3/8 bolts into captive nuts. My plan is to weld crush tubes through the cross member with spreader plates and bolt through the seats' front legs and cross member to secondary legs welded to the runners. Which sort of presupposes that option 1 above is satisfactory.
Supplementary question to the above: How to I deal with 'incompressible' air gaps, in this case the channels pressed into the floor pan?
Is that enough info? I could take photos, draw it up or whatever, but the principles must be relative straightforward or at least common to other vehicles being certified.
Thanks in advance,
Simon.
