Bullbar

Will a bullbar from a GQ fit a series 1 GU? What other parts are interchangable? The GQ is an 89 TB42s the gu is a series 1 but was origionally a 3Ltr and has been converted to a 4.2TD with an silvertop turbo motor from a GQ but is still running all the 3ltr running gear.
Thank in advance

No they will not fit.......

Are any part interchangeable?

Diffs are wider on a GU,
Remember it was to update with a new model so not many carry over parts

Springs and shocks will fit.

And wheels

The interior light switch rubber covers from GQ will fit GU rear doors I believe... 😜
