any mk2 one will fit. 1.0-1.6 is 7", 1.8 are 9". 9" obv an upgrade, but also more tricky to squeeze in. you can do it engine in though believe me, i managed on my mk2 gti 8v tho it was a struggle. you;'ll have much less hassle since its a carby, more room.
corrado and passat will also have the one you need, just make sure it has a clevis pin on the back not like a ball on the end of a pin (mk3 fitment)
