Re: One of life's goals nearing reality
Just be careful with the 9" identification- 8" or 8 3/4" or what ever you want to call them look extremely similar, and don't have bolts on the back like a 9". They're very hard to tell apart unless its out of the car, just something to be aware of.
If the back of the diff housing centre has a step in in (rather than a smooth continuous bulge), its very likely its a 9".
If it looks like a 9" but has a continuous bulge (with or without dimples), then it's likely its an 8"/ 8 3/4"- whatever.
Some 9" have a smooth bulge across the beck, but not the XY ones.
Also, confirm its actually a XW/XY length 9". Measure ******ds from the spring mount to the end of the diff flange. If its approximately 80mm, its XW/XY. If its more like 130mm, its XA-XC- not original fitment for the car, and worth a fair bit less than a XW/XY one.
If its an original 351c, the compliance plate should have K code (351 2v) or T code (351 4v, as in GTs).
An original 351 should have the 54H body shell which is the same as GT. Therefore it should have the larger radiator and big, reinforced radiator support, bigger fuel line, and factory exhaust hangers in the inner rear quarter panels.
A factory 351, 4spd 9" XY is a big dollar car, so don't be disheartened if the numbers/ codes don't match up- if its a good car at the right price, it doesn't really matter what it was originally fitted with.
Hope this helps,
Cheers,
Matt
