i finally got the factory bolts undone (used an impact
wrench) to remove the bottom
frame. The seat i bought tilts forward, so it appears that the
position of the locked seat is a little more than the 51's more
upright position. The locking lever is located on the passenger side only. This
seat has built in retractable seat belts & a middle belt. today I will take some
pics and investigate more how the fit is in our stock frame. At first glance it
looks like the 51's frame sheet metal @ the back corners has to be
removed. This is not the case so far. I'm much taller than Caroline so she will most likely have to use a pillow. The new seat is more square. The astro seat is about 21'' tall, so I'm about 3-4'' shorter than stock.
now that i removed the seat belt attachments the astro seat fits inside the stock 51 frame work nicely.
the reclined position of the astro will need to be proped up in the back of the frame work because of the angle of recline.
