Barb, does your Monty have buckets on now? if so you can just add
spacers between track and seat frames.you might need to egt longer bolts
depending on how high you want to go, we just got rid of some black buckets
off a 70ish olds,and the driver was elec.(back&forth,up&down) olds,buick
and chev use the same frame pretty much,
