I have two pedestal seats from a van that I would like to mount in my MC9. I am unable to access under the seats for bolts. What do you all think about 1/2 inch lag bolts. They would bolt through the seat base, through laminate floor, through 1/2 inch new plywood over the 1/2 in old bus plywood floor. Would these bolts be sufficient to hold the seats in place?
Thanks for the advice.
I don't know about an MC9 but I would think that lag bolts would not be a good idea. In the event of a crash or sudden stop they might just give way, that would not be good. Is there a way to run long bolts or long ready thread and make it more secure by running them through some steel plates on the bottom side?
Just a thought,
Paul

Lag bolts are just to keep stuff from sliding around. Not for holding seats with people
or pets in them.
You will need to probably make mounting plates to attach the pedestals to that will reach to spots where you can securely bolt into a subframe or something.
Are these seats to be used for the driver/copilot, or are they for lounge use when your parked?
Kwood,
For the copilot seat you might be able to get bolts through the area where the air door lock cylinder is, but I think you will have to remove the right front wheel well from outside to access the area under the finished floor for a seat.
Kwood, I do not know about Your MC9 but on My 7 I can acess the area where My seat bolts pass throught the floor from the spare tire compartment. Please do not use lag bolts. Use only grade 8 or 5 to bolt Your seats down. Use a back up plate or large fender washers on the under floor side in the event the worst happens. Having a heavy seat and person ejected would not be good. Lag bolts are not of the grade necessary for the application even if the subtrate would retain the threads. Regards, John
Thanks for the replies. I will not use the lag bolts. I will find some way to access the underside.
Kevin,
I'll tell you what I originally thought about doing for mounting the copilot seat.
Acquiring a steel plate ½" x 2' x 3' and 3 pieces of 1-1/2 " x 2' angle iron.
Then bolting a piece of the angle (web up) to the sidewall at floor level.
Next piece of angle bolted through the floor into the frame at the edge of the ramp (web down towards the ramp).
Next angle to that angle with the web facing toward the angle on the wall.
Now you can bolt the ½" plate down to these angles and mount the seat anywhere on that plate.
The plate will be 1-1/2" off the finished floor, where a slideout to cover the step well would hide nicely.
