dumb rear end question

[baz-r]

ok i have my sierra ready for the chop and now im on sorting the chassis.

all i need do is make my mind up on tube and cut , flat pack , fully welded semi or full

welding in no prob its just the hassle of sorting the little brackets etc
it seems that by the time i buy the cut tubes the plates and the brackets im not that far of the cost of a chassis in welded form or am i wrong?

so i see some of the flatpacks and the welded chassis come in the ally or fiberglass back end so what is the diffrence? is it just the round tube frame that makes the rear of the car is ommited?
or is it a bit more than that?

if any of the suppliers could pm me on whats fitted and not fitted to thair welded chassis kits that would be realy good.

thanks of all of your input so far guys

I am sure Handy will hep you out. I am goingto have to convert my rear end on my chassis once I have it as I want a glass rear end and it's buitl for ally.

Baz-r.

basically you are right in your thoughts......... the tubes used for the ally tub are not needed for a GRP tub,

but there is an extra tube (supplied in the flat packs) that is cut to size for fitting a GRP tub.

its a nice position to be in, with the choices you have mentioned...buy steel/flatpack or fully welded chassis, it all depends on how much/how little you wish to do & also your build budget,

if you have any questions, don,t hesitate to get in touch. (regardless whether you go buy steel/ flatpack/built chassis)

good luck in making your choice of which way your build will begin by.

if it helps, i have some photos showing the rear of the chassis for fitting a GRP tub, let me know if you want them put on this thread.

A pic of the two rear ends would be good so I can get my head round it.

my pics are on the desktop at home...............

but there is a thread titled " question about Saturns/Fabbys rear end" in the bodywork section, last thread on 2nd page.......

that thread shows the rails & a drawing of the boxed tube needed for fitting a GRP tub.

hope this helps (soz, can,t do linky things )

cheers

its 17.6mm at a 5 degree upwards angle ,

hope that helps,
the dimensions are taken purely from my own fabrication of how i thought it was best to create a strong mounting point for the GRP tub,

also it gives a nice strong area to attach the back stays of the roll bar ( down into the extreme bottom corners of the new grp tube (i,ve named it GRP1 in my chassis kits) .
