measured up and ordered a new aluminum radiaror...

hell BMR may be less expensive but the stuff is as good as quality as any ive seen...and the anti roll bar set up made my ride go from a death trap to a car thats fairly easy to drive.. I have actually put my ride into the guard rail it was so bad.. and now it looks pretty sweet and works even better..also was so freekin easy to install it was rediculious and to think I was going to have a weld in set up professionally installed before i found the BMR kit...

I believe all gm 10 and 12 bolts are c-clip rear ends, and the big 10's have 8.8" ring gears and the 12 bolts have I believe a 8 and 7/8" ring gear and the bigger the ring gear the stronger the rear...jmo I have a 12 bolt with c-clip elimator kit , strange axles (35 spline) strange spool and richmond 488 gears and have never had 1 problem out of it and I beat the crap out of mine on a regular basis... hope this helps..Lee

I started out about 10 years ago with racing my monte and my forst motor was a 406" stock crank and rods, trw 12.5 to 1 compression a crane solid flat tappet cam 520 540 lift, gm phase II bowtie heads mild port job by jim terrian form mich, port matched victor jr intake 2" spacer and a 800 cfm holly dp, 1-7/8" headers a 400 turbo and 4500 stall *" converter and 488 gears and it was a beast!!! would run 10.80-90's all day!! I eventualy put the motor in a 78 monza and shot a 250 shot on it till I finally grenaded it!! it ran 9.40's in a 2800 pound monza with 10 tires through mufflers on the hose... I dont think i had more than 3000 into the whole motor..

here is a pic of mine with the BMR upper and lowers

I have the BMR anti roll bar on the rear of my 72 and before I installed it mine was twisting something fierce and put me into the guard rail!!! after the install it leaves straight as an arrow, level and actually took all the air out of the rear airbag too...and it 60 ft is in the 1.4's.. and it looks pretty cool too!!

I have got bmr tubular a-arms and bmr rear anti roll bar and they are very nice pieces... also have hotchkiss rear upper and lowers and my 72 hooks like a dream!!
