Well, have had a couple of requests about the seat and subframe modifications. Took some pics, but we've had crappy weather in dallas the last several days so they're inside and may be a little dark.
The seat is a motollana unit, but recently DCC has started carrying their own that look very similar too.
Here's the bottom of the seat. You can see where I had to cut into the rear section so I could fit the cover flush.
The rear hoop was cut off the subframe and brackets welded on the front and back. The the front tabs slide into the front bracket and the seat bolts down to the rear section.
So far so good, no problems with it. I know the front bracket has a pretty large moment arm on the weld, but it's made out of 3/16" steel angle iron and has a pretty large weld running on it.
There's a sheet metal part that covers up the underside of the seal and has the brake light and turn signals mounted to it.
