Those dont look to me to be the late type as used on bays and type 25s to be honest. You need to check whether all t25 runners are the same. My seats are from an early t25. My swivels are from an early type 25. However i have a set of late bay seats. They also fit onto the same runners. My point being that you need to check but if in doubt then buy runners too. Late, late bays and early t25s are interchangeable.
Don't really know as I've only had non standard seats - but I don't think they are too high - but I am only 5'7" with short legs and they are OK for me.
i didnt answer the question but id just get some runners. As i said above i think there are two types of runner on late bays.
I got some Porsche tombstones, which are only slightly higher base than our originals, and my wife can just about reach the pedals, she is technically a dwarf thou.
No problem and I wasn't expecting you to run out in the rain to get some, just maybe for some absurd reason you may already have some pictures of late runners
Now even im confused... See; http://www.justkampers.com/211-801-345-g-seat-runner-vw-t2-bay-1974-1979.html
For what it's worth I have T25 seats and the JK runners with aftermarket swivels, all works well and her indoors can reach the floor and she is 5'3" on a good day
i have the two front seats that came out of the bus when we got her, they were badly fitted by the PO and i took them out, there is no seat runners in the van but im not sure if there are any other parts missing from the seats following the bad fitting,
