AX-15 Mounting plate/trans mount for crossmember

[Pete M]

you can swap 84-87 with 87-90 by keeping the old clip style from your old cluster and putting it on the new one.  but 87-90 are waaaaay more common to find in 6cyl (which is important to have an accurate tach).  the tach in most clusters is technically adjustable, but it's a pain in the butt (it's a little pot on the backside of the guage) and I'm not even sure if all years can do that.  every one that I've opened up can be tweaked, but I've heard not all can.

Ok, thanks, now I actually know if a cluster is what I need or not instead of taking out 4 clusters all from 91+ XJs like I did at this one yard.

Look at the screws on the face of the speedometer.  Flathead screws denote one style and phillips denote the other.  It's been so long I don't remember which is which, but it's an easy way to identify the clip style without having to pull the whole cluster.

Ok thanks, but back to the crossmember. The other bolt holes that are further back so you can relocated the crossmember, they aren't threaded. The bolts that came out of the original holes are self tapping, so should I just use those to make their own threads, or are those known to be a bad idea, and I should just get a tap for them?

[Pete M]

personally I would tap the holes rather than trust the 30 year old screws to still do their job.  

[Warren99]

Ok, not sure what I'll do yet.

I'm gonna borrow a tap set from a friend and do it soon.
