[Fot] Has anybody put a TR4 tub on a TR6 chassis?

[yellow04]

I figured this was the place to ask this question.

I am selling an early TR4 project/parts car on Craigslist and just got a 
question that I can't answer. Will a TR4 tub that goes on the ladder 
frame mount to an IRS wishbone frame?

Thanks.
